WHEN ALIENS ATTACK, PARALLEL UNIVERSE:Clockwork and Creation
COMETS: THE REGULAR VISITORS TO OUR PLANET
Scientists have discovered that our solar system is very unique. Earth is located in a star system that is by no means the norm in space. As a matter of fact, our solar system appears to be the exception. A stunning exception, in the way it’s laid out to actually foster the very conditions on Earth which makes life possible. In the universe at large, chaos, explosions, and mind-bending collisions between massive celestial bodies appear to be commonplace. After you watch this video, you may never see our little blue planet quite the same again.
Robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information for us right now all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn; several others on their way to smaller bodies; and a few on their way out of the solar system entirely. On Mars, a rover called Spirit has just been officially left for dead, after two years of radio silence from it -- but its twin, Opportunity, continues on its mission, now more than 2,500 days beyond its originally planned 90-days. With all these eyes in the sky, I'd like to take the opportunity to put together a photo album of our Solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries.
Some credible witnesses have identified a Deep Underground Military Base at Dulce, New Mexico as the primary location of a Beyond-Black alien-human hybrid breeding program.
This Dulce, New Mexico DUMB operates under authority of the USG but is under the actual day-to-day control of private offshore foreign defense contractors of the Secret Shadow Government (SSG).
This Beyond-Black program is a joint venture between aliens and MJ-12, which is the core controlling group of the Secret Shadow Government.
It is believed by some who have been “involved” and have been “allowed” to “leak information” that this secret alone is the initial reason for the SSG and the main reason for the creation of the US National Security State.
Historically, this subject has been classified Beyond-Black.
Since this whole subject has historically been Beyond-Black and strictly verboten with perhaps hundreds of assassinations used to keep it secret until only the last several years, after which gradual leaks have been orchestrated within MJ-12, it is still only possible to get an glimpse of the truth from various sources rather than any official USG declaration (which may actually be coming soon, voluntarily or forced by the aliens according to treaty stipulations, allegedly). For now the best one can do is pay attention to actual “leaks” from respected or credible sources as well as their view and speculation on these oblique matters. Anyone who doubts that significant and highly valid leaks have occurred and still continue at an even higher rate can do some deep research on Dr. Steven Greer’s disclosure project and acquire copies of all the testimony that is now available on a published complete DVD set for the meeting recently in 2013 in Washington DC. It has also been suggested that there have been consecutive “treaties” between USG and later SSG officials for joint ventures and technology sharing which involve “arrangements” with aliens providing Beyond-Black technology of a wide variety in exchange for access to human subjects, their genes by permitted abductions, and assistance with the biochemical engineering required to attain their goals of hybridization. And now for the strange part of the story.
The specific goal of these aliens for creating these alien-human hybridizations is claimed to be the extraction, distillation, and replication of the human spirit within the developed hybrids. As the narrative goes, the top aliens at the Dulce Base are Reptoids who are the controllers. These Reptoids allegedly have previously developed biological androids with functional brains and bodies and consciousness, with the characteristic of being “hived-type” group-mind based creatures. Thus this is their basic issue and one which seems to be forever elusive.
In practical terms this means that they cannot create and instill the “spirit” that only God Almighty creates no matter how hard they strive and toil.
So far the aliens and human technicians and scientists who work together at Dulce have not been able to create and instill the human spirit in these Reptoid hybrids.
Reptoids have been reported to have been here on planet earth for thousands of years, residing in deep underground abodes and maintaining the ability to fly through the earth’s atmosphere in anti-gravity craft (AGCs) for interplanetary or inter-stellar travel.
Depiction of the ancient Nephilim or Draco type Reptoid, reported to be very aggressive
Some have reported that the alien controllers are “Reptilian” a larger species that have been here on planet earth underground for hundreds of years, perhaps being the Nephilim or Anakem mentioned in the Bible and other ancient texts. As the narrative goes these Reptilians have been prevented by “rules of play” present in the universe from residing above ground and must hybridize in order to be allowed to do so, but can move through the atmosphere and space in anti-gravity craft (AGCs) and supervise human abductions.
Some researchers such as David Icke, very popular in American and especially Europe and the UK have claimed that the British Royal family and many other super elites that control the world are reptilian hybrids and even that they have the ability to apparently shape-shift which is some sort of strange inter-dimensional cloaking ability. Years ago I rejected Icke’s view out of hand but after so many recent releases from credible former military and defense contractors, a substantial number of his claims are becoming more plausible all the time.
Are serious Alien Treaty violations being tolerated by the SSG?
Some credible intel folks have leaked reports that these Reptilians have a taste for raw meat, especially human and have been responsible for abducting and butchering significant numbers of humans “disappeared” from Federal Parks and country roads. This of course is a complete violation of prior treaties but is allegedly tolerated because the alien technology shared in exchange has been so great.
Others have claimed that there are certain alien groups which have a distinct human appearance such as the Nordics who are now fully hybridized in small but growing numbers and want to help humans resist an alleged planned invasion by subterranean Reptoids who are luciferians, evil to the core and allegedly working very hard to set up a Globalist NWO system using the “mystery Babylon religion” which involves the use of Babylonian money-magick, pernicious usury war, starvation and pestilence to reduce the human population of earth and prepare the way for a complete Reptoid takeover characterized by a New Roman Caesar of the ages seated in Jerusalem in a specially built NOW temple based on the design of Solomon.
A kinder gentler Reptoid hybrid?
It is allegedly the belief and absolute obsession of the Reptoid leaders that the capture and holding of Jerusalem and mount zion is their ticket to rule the earth and to be able to establish a complete worldwide luciferian kingdom with them holding absolute Caesarean power, using a small remnant of humans captives as worker bees until the technology of trans-humanism become well enough developed to permit a whole new race of subservient serfs that are alien hybrid being with spirits.
What exactly is this Beyond-Black secret alien-human breeding program now being run by a joint coalition of alien and MJ-12 appointed SSG scientists?
This program is allegedly run in at least one Deep Underground base (DUMB) at Dulce, New Mexico. It is staffed by scientists and technicians hired by offshore based private defense contractors who answer only to the Secret Shadow Government (SSG) and not in any way to Congress of the USG, which is actually unconstitutional and highly illegal as well as seditious and treasonous.
Russian Prime Minister Medvedev has acknowledged that aliens have visited earth and there is a top secret fuile that accompanies the nuclear launch codes at all times.
Esteemed UFO and break-away-society researcher Richard Dolan believes there is substantial evidence that alien technology has been shared with the USG DOD contractors and also believes that there is an underground base at Dulce, New Mexico.
Other respected individuals including Timothy Good and John Lear believe that there is an underground alien base at Dulce, and Philip Schneider who worked there during construction went public and was allegedly murdered for telling his story about an alien human shootout in which he was seriously injured.
Here is a short video clip purported to have been secretly taken inside the Dulce, NM DUMB and smuggled out.
The Dulce, New Mexico DUMB is alleged to house a sophisticated lab for developing human-alien hybrids in various forms.
Dulce is deep underground, is constructed with at least 8 different levels, and with each level having a specific purpose as well as special security rules and procedures. One floor has been called “nightmare Hall” where allegedly human-alien hybrids are caged and when human visitors come close, these unfortunate creatures cry out and beg for help and release. Allegedly workers have been told that they are breeding failures and very dangerous beings with criminally insane personalities and are extremely conniving and convincing and if one converses with them they risk becoming mind-kontrolled under their psi-powers which have been bred in.
Are there Super-Soldiers now operational that employ alien implant technology and even some with injection of specific alien genes for super-intelligence super strength and hardened battle attitudes?
It has also been alleged that in some setting and labs above ground, alien genes have been spliced into human to produce “super-soldiers”, some of whom have been reported to have super-strength, super stamina, very high IQ’s of 200 or greater and very strong psi-power.
The first super-soldier to go public was Robert Duncan O’Finoian who appeared on the Jesse Ventura TV show, Conspiracy Theory. Just recently others have gone public and been interviewed by Kerry Cassidy of the Camelot project. It is now recognized by some insiders that many special ops, black ops, spooky teams and special operators have implants based on alien technology. Are some super-soldiers conditioned with alien technology and are some actually Human-Reptoid hybrids who serve as special G-7 black ops? It has been reported that some of these super-soldiers are actually human-Reptoid hybrids, and although they look completely human, they have claimed to have some reptilian characteristics such as the easy ability to engage in targeted assassinations as black ops. And it is also generally recognized that a significant number of super-soldiers have been conditions with alien “Draco” or Reptoid technology also know as black arts of the “old Black Nobility” passed down all the way from ancient Babylonia.
A substantial number of super-soldiers have reported that they were conditioned with severe trauma methods typically used by Joseph Mengele who was reported to have gained such information directly from aliens himself as a part of his worship in the cult the “Black Sun”. And if rumors are correct, numerous special ops are injected with alien genes to enhance performance in the battlefield, dull their conscience and provided with alien memory removal techniques afterwards to allow them to forget unpleasant activities on the battlefield or during any special deployment. Many special ops may have no idea that they have been conditioned or have had satellite track-able id chips inserted in their molars or under the skin.
And a fair number of these have reported the regular administration of IV bags of scopolamine as well as additional brain wiping treatments treatments while being hooked up to a “psychotronic suitcase”. These treatments appear to fail a significant amount of the time, especially after 15 to 20 years when these super-soldiers start remembering many unpleasant things from the past as well as the severe torture used to “soul murder their minds” and disassociate them to produce numerous identities.
Were super-soldiers deployed at Waco?
One infamous “super-soldier” situation involved the Waco raid where the FBI is alleged to have deployed a portable tunnel drilling machine from an out building to tunnel into the “compound”. On that final day while the US Army Tanks bashed in the walls and used flame throwers to start the fires, the black ops entered the compound and began executing those inside with gunfire.They intended to shoot the children with poisoned tranquilizers to humanely kill them, but they did not realize they were locked in a bus buried underground and could not get to them. After the op they claimed they were taken to a motel as part of a normal “erasure routine” and hooked up to IV bags of scopolamine and the “psychotronic suitcase” with electrodes to the head. In this case they erasure failed to wipe clean their traumatic memories of the op and they were all very agitated and very upset. When some of them realized the full extent of their actions they decided to stop doing all such actions and go to Congress for help.
Allegedly they were so upset afterwards they went to DC Attorney Paul Wilshire who was a good friend of Sarah McClendon, and he agreed to represent them. Attorney Wilshire prepared a detailed legal brief describing what happened and a proposal that this team of twelve appear before a congressional committee and testify truthfully as to what really happened as long as they received grants of complete immunity. A deep search on the Internet can probably provide a copy of most of this legal brief with the names of the black ops redacted.
Paul Wilshire delivered the brief to Janet Reno and was never heard from again. A few weeks later he was found by Sarah McClendon dead in his apartment after she called for help because he wouldn’t answer his phone or a knock at the door. His autopsy report stated that he died of un-ascertainable causes. And of course these black ops did not appear at the Congressional Hearings on Waco.
Have human looking hybrids actually been stationed inside the pentagon and the SSG deep black programs in managerial or consulting roles?
It has been reported by several respected individuals who worked in sensitive Pentagon positions that there have been human appearing alien hybrids actually stationed inside the pentagon working on sensitive projects and even assuming high management positions due to their superior IQ’s and secret Psi-powers. Psi-powers are best defined as super-natural appearing spiritual powers that allow individuals to have perceptions and power over other people’s thought and actions that would not normally be possible. Have high level progressively revealing “leaks” become policy and are they required as a part of human-alien treaties? Apparently highly placed individuals have been instructed to leak this information as part of a strategy to push complete or near complete disclosure of the “alien presence” and their agenda despite the reluctance of those at the top of MJ-12 and their controllers to allow this.
In the past up until several years ago there was a “no-talk rule” that was strictly enforced by with-prejudice terminations (file name for first degree. Premeditated murder supposedly justified in order to protect “national security” which translated really means in order to protect the security and power of the “national security state” which in reality is the world’s second largest RICO crime syndicate (Centralized world banking is currently the largest RICO crime syndicate).
Are there different coalitions within MJ-12?
Yes, there are two main coalitions that have formed and the younger one that wants complete disclosure has allegedly been approached separately by alien representatives that have suggested that they can push hard now for disclosure and that the senior MJ-12 folks have been “barred” from stopping it.
It is alleged that there is an over-riding agreement still in place that requires complete disclosure by the end of 2015. And if this is not attained, fleets of alien anti-gravity craft (AGCs) will allegedly descend on the capital cities of the world to force disclosure.
There are different viewpoints of what aliens are among respected UFO researchers.
There are several main schools of serious UFO/Alien researchers, with each group believing that aliens are real entities. One group believes that these are off-planet alien entities that have come to earth to “provide a better way” after nuclear weapons were developed and deployed, and this is being done as representatives of a “star fleet”, an interplanetary organization of different aliens which is now approaching earth leaders in order to prevent them from going wild with this nuclear bomb technology and harming the universe, or at least the part they inhabit. This group believes that these star fleet aliens are basically very advanced, good entities that only want to promote peace and protection of the Universe for every entity’s good.
Another group believes that these alien entities are bifurcated into different types, with one type, alien Reptoids, who live in underground bases before humans particularly. They believe that these Reptoids are particularly aggressive and lords over large and small grays which are subservient to these dominant ones, with the small grays very submissive cloned androids, that is genetically created, spiritless remote slaves. This second group believes that aliens thus pose the greatest current threat to mankind that has ever occurred and any and every possible action must be taken to gain their technology in order to have the tools to resist them and eventually gain victory over them.
And a third group believes that there are tall white Nordic type aliens that live in the colder areas of the earth in underground bases in Antarctica and the southern part of South America. It is alleged that this group approached the Vrils and the Thule party and supplied their advanced alien weapons systems, knowledge of nuclear energy and bombs, as well as anti-gravity technology to the Nazis who in turn shared it with the British and Americans in a special agreement in 1943 under Operation paperclip when they realized the war was going to be lost. It has been reported from credible sources that the Tall White or Nordic aliens continue growing in height as they age and eventually “outgrow” their internal organs which causes illness and death. It was these Nordic types that Hitler was informed of by the Thule party officials who allegedly gained contact with them and their technology through the Vril women.
Some within MJ-12 view cooperation with alien hybridization programs as a necessary evil in order to continue to gain desired alien high technology.
Within MJ-12 there is also a split of how these aliens are viewed with most viewing them as deceptive, self-serving and a necessary evil that the SSG must cooperate with in order to develop enough advanced weapons technology with which to effectively resist them and defeat them when an expected attempt is made to invade planet earth.
It is generally believed within MJ-12 that there are “rules of play” to the Universe set in place that require a certain mass or majority of humans to grant consent in order for any invasion or even any generally open appearance and establishment of a joint alien/civilian world government, which is allegedly what the top alien controllers really want but only the older MJ-12 folks want. However many inside MJ-12 believe that unless the alien agenda is deployed, the world will self-destruct due to mass pollution, disease starvation, disease and pestilence.
Certainly there are some newbies in MJ-12 that believe that some senior controllers have been effectively mind-kontrolled and “taken over” by the aliens from working too close with them.
So it seems that MJ-12 is sort of in a tough spot, between a rock and a hard place. Perhaps one way to delay any “alien descent” is to initiate a nuclear WW3 which according to rumors is what aliens fear the most, contamination with radiation because they are especially sensitive to certain kinds of this.
Some inside MJ-12 believe that if world leaders work together to radically reduce the world’s population by at least 80% and institute draconian controls over all peoples while staging geo-engineered terra forming, that the aliens will agree to proceed with their planned occupation of Africa and forego a complete world takeover.
It has been alleged that the Reptoids are pushing hard for very Draconian and radical depopulation of the earth and Agenda 21 controls.
So the alleged choice is cooperation with the alien required geo-engineered terra-forming, radical depopulation, and a systematic roll-out of Agenda 21 accompanied by the re-population of the earth with alien-human hybrids which will instinctively “serve the central hive”, or the alternative to suffer a complete alien takeover with deployment of their much more drastic depopulation solutions.
The operating philosophy of the alien leaders who meet and work with SSG personnel in these joint alien—hybrid breeding experiments is that the human race is damned to destruction unless re-engineered to be instinctively hive-oriented hybrid with the collective greater good as its main goal.
Allegedly top MJ-12 folks in the past have played along with this “alien agenda” in order to gain access to enough high technology to be able to fight them effectively in a future war of the ages, but some who are close to the situation see this differently.
These who see it differently believe that these top MJ-12 have been mind-kontrolled and compromised and are now “hived” to serve the alien leaders, having their souls extracted and replaced with a hive entity, some would describe as a demonic or Jinn entity.
The final battle between Humans and Aliens for the control of Planet earth’s surface?
Here is one scenario of how the world situation could play out. The Mideast could go hot and generate a nuclear exchange between Russia, Israel and America.These weapons would be high yield as far as explosive potential but low yield radiation afterwards. Israel would be completely destroyed and most of Russia and America would be devastated and the USG would be completely decapitated. The SSG Dumbs would also be devastated by pre-placed advanced bio and nuclear devices featuring anti-matter lithium 7 mini-nukes.
This would be followed by a horde of alien entities coming out of the Pacific basin to form an alliance with the Chinese government which would amass a great army and mobilize to invade the Mideast. Alien advisors would inform top Chinese Generals that an off planet most evil alien force was headed for earth and would be invading it to take over.
And that only if they combined forces could they effectively defeat this incoming evil alien force.
Some believe that this will be the final battle of the ages, the complete mobilization of planet Earth after being hijacked by evil luciferian alien-human hybrids who infiltrated and controlled the highest echelons of human government church and banking and did everything they could to tempt humans to think and act with evil and hate towards their fellow man, continually “stoking the flesh” and promoting all the “sins of the flesh”, knowing this would destroy normal human society and the family and sex roles and make it easier to install a Globalist NOW luciferian based world government and system.
Until publicly proven and confirmed by the Controlled Major Mass Media (CMMM) or an actual huge sighting by thousands in a public area, this is all still speculation based on informed rumors.
Now this is all speculation and it’s anybody’s guess what will really happen. The conservative Christian Biblicists, including a substantial number of Putin’s Orthodox Clergy in Russia believe that this is all specifically predicted and described in the Kings James Bible and other earlier scriptures. They also believe that the so-called actual invading aliens from outer space in the final battle will turn out to be God’s army against the aliens (Dracos or Reptoids)) which come up from underground to fight at the battle of Armageddon. Only time will tell if these folks are correct or not.
When a rather large-sized (M 3.6 class) flare occurred near the edge of the Sun, it blew out a gorgeous, waving mass of erupting plasma that swirled and twisted over a 90-minute period on February 24, 2011. This event was captured in extreme ultraviolet light by NASA's Solar Dynamics Observatory spacecraft . Some of the material blew out into space and other portions fell back to the surface.

A closeup of the solar surface. Part of the largest sunspot in Active Region 10030 recorded on July 15, 2002, with the Swedish 1-m Solar Telescope on La Palma. The width of the cells near the top of the image are roughly 1,000 km. The central part of the sunspot ("the umbra") looks dark because the strong magnetic fields there stop upwelling hot gas from the solar interior. The thread-like structures surrounding the umbra make up the penumbra. Dark cores are clearly visible in some of the bright penumbral filaments that stick out into the umbra.

NASA's SOHO satellite watched as a fairly bright comet dove towards the Sun in a white streak and was not seen again after its close encounter on May 10-11, 2011. In this coronagraph the Sun (represented by a white circle) is blocked by the red occulting disk so that the faint structures in the Sun's corona can be discerned. Interestingly, a coronal mass ejection blasted out to the right just as the comet is approaching the Sun. Scientists, however, have yet to find a convincing physical connection between sun-grazing comets and coronal mass ejections. In fact, analysis of this CME using images from the Solar Dynamics Observatory shows that the CME erupted before the comet came close enough to the solar surface to interact with strong magnetic fields.

NASA's project Morpheus lander is seen bursting into flames during a test at Kennedy Space Center, Florida, on August 9, 2012. During a free-flight test of the Project Morpheus vehicle at the Shuttle Landing Facility, the vehicle lifted off the ground and then experienced a hardware component failure, which prevented it from maintaining stable flight. No one was injured and the resulting fire was extinguished by Kennedy fire personnel. Project Morpheus is a vertical test bed designed by NASA, demonstrating new green propellant propulsion systems and autonomous landing and hazard detection technology. (Reuters/NASA/Handout) #
The "Mighty Eagle" soars above the tree line on August 16, 2012. The vehicle was "open loop" -- navigating autonomously without the command of the onboard camera and flying on a preprogrammed flight profile. This NASA robotic prototype lander sailed to an altitude of 100 feet during another successful free flight August 28 at NASA's Marshall Space Flight Center in Huntsville, Alabama. The test is part of a new series of free flights testing the robotic prototype lander's autonomous rendezvous and capture capabilities. (NASA/MSFC/Fred Deaton) #

On Mars, NASA's Rover Opportunity catches its own late-afternoon shadow in this dramatically lit view eastward across Endeavour Crater. The rover used the panoramic camera (Pancam) between about 4:30 and 5:00 p.m. local Mars time to record images taken through different filters and combined into this mosaic view. Most of the component images were recorded during the 2,888th Martian day, or sol, of Opportunity's work on Mars (March 9, 2012). At that time, Opportunity was spending low-solar-energy weeks of the Martian winter at the Greeley Haven outcrop on the Cape York segment of Endeavour's western rim. Opportunity has been studying the western rim of Endeavour Crater since arriving there in August 2011. This crater spans 14 miles (22 kilometers) in diameter, or about the same area as the city of Seattle. (NASA/JPL-Caltech/Cornell/Arizona State Univ.) #

This image is from a test series used to characterize the 100-millimeter Mast Camera on NASA's Curiosity rover. It was taken on August 23, 2012, and looks south-southwest from the rover's landing site. The 100-millimeter Mastcam has three times better resolution than Curiosity's 34-millimeter Mastcam, though it has a narrower field of view. In the distance, there are dark dunes and then the layered rock at the base of Mount Sharp. Some haze obscures the view, but the top ridge, depicted in this image, is 10 miles (16.2 kilometers) away. Scientists enhanced the color in this version to show the Martian scene under the lighting conditions we have on Earth, which helps in analyzing the terrain. (NASA/JPL-Caltech/MSSS) #
Every day until Sunday, December 25, this page will present one new image of our universe from NASA's Hubble telescope.
A "Rose" of a Galaxy. In celebration of the 21st anniversary of the Hubble Space Telescope's deployment into space, astronomers at the Space Telescope Science Institute pointed Hubble's eye to an especially photogenic group of interacting galaxies called Arp 273. Pictured here is the larger of the two galaxies, known as UGC 1810. It has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light. A possible mini-spiral may be visible in the spiral arms of UGC 1810 to the upper right. It is noticeable how the outermost spiral arm changes character as it passes this third galaxy, from smooth with lots of old stars (reddish in color) on one side to clumpy and extremely blue on the other. UGC 1810 lies in the constellation Andromeda and is roughly 300 million light-years away from Earth. More info here. (NASA, ESA, STScI/AURA)
This collection of dazzling stars is called NGC 6611, an open star cluster that formed about 5.5 million years ago and is found approximately 6500 light-years from the Earth. It is a very young cluster, containing many hot, blue stars, whose fierce ultraviolet glow make the surrounding Eagle Nebula glow brightly. The cluster and the associated nebula together are also known as Messier 16. Astronomers refer to areas like the Eagle Nebula as HII regions. Extrapolating far into the future, this HII region will eventually disperse, helped along by shockwaves from supernova explosions as the more massive young stars end their brief but brilliant lives. In this image, dark patches can also be spotted, punctuating the stellar landscape. These areas of apparent nothingness are actually very dense regions of gas and dust, which obstruct light from passing through. Many of these may be hiding the sites of the early stages of star formation, before the fledgling stars clear away their surroundings and burst into view. More info here. (ESA/Hubble & NASA) #
A dying star, IC 4406, dubbed the "Retina Nebula" exhibits a high degree of symmetry; the left and right halves of the Hubble image are nearly mirror images of the other. If we could fly around IC 4406 in a starship, we would see that the gas and dust form a vast donut of material streaming outward from the dying star. From Earth, we are viewing the donut from the side. This side view allows us to see the intricate tendrils of dust that have been compared to the eye's retina. In other planetary nebulae, like the Ring Nebula (NGC 6720), we view the donut from the top. The donut of material confines the intense radiation coming from the remnant of the dying star. Gas on the inside of the donut is ionized by light from the central star and glows. Light from oxygen atoms is rendered blue in this image; hydrogen is shown as green, and nitrogen as red. The range of color in the final image shows the differences in concentration of these three gases in the nebula. Unseen in the Hubble image is a larger zone of neutral gas that is not emitting visible light, but which can be seen by radio telescopes. One of the most interesting features of IC 4406 is the irregular lattice of dark lanes that criss-cross the center of the nebula. These lanes are about 160 astronomical units wide (1 astronomical unit is the distance between the Earth and Sun). They are located right at the boundary between the hot glowing gas that produces the visual light imaged here and the neutral gas seen with radio telescopes. We see the lanes in silhouette because they have a density of dust and gas that is a thousand times higher than the rest of the nebula. The dust lanes are like a rather open mesh veil that has been wrapped around the bright donut. The fate of these dense knots of material is unknown. Will they survive the nebula's expansion and become dark denizens of the space between the stars or simply dissipate? More info here. (NASA and The Hubble Heritage Team, STScI/AURA) #
Hubble catches Jupiter's moon Ganymede just before it ducks behind the giant planet. Ganymede completes an orbit around Jupiter every seven days. Because Ganymede's orbit is tilted nearly edge-on to Earth, it routinely can be seen passing in front of and disappearing behind its giant host, only to reemerge later. Composed of rock and ice, Ganymede is the largest moon in our solar system. It is even larger than the planet Mercury. But Ganymede looks like a dirty snowball next to Jupiter, the largest planet in our solar system. Jupiter is so big that only part of its Southern Hemisphere can be seen in this image. Even though Jupiter is some 730 million kilometers (450 million miles) distant in this image, Hubble's view is so sharp that astronomers can see features on Ganymede's surface, most notably the white impact crater, Tros, and its system of rays, bright streaks of material blasted from the crater. Tros and its ray system are roughly the width of Arizona. The image also shows Jupiter's Great Red Spot, the large eye-shaped feature at upper left. A storm the size of two Earths, the Great Red Spot has been raging for more than 300 years. As Ganymede passes behind the giant planet, it reflects sunlight, which then passes through Jupiter's atmosphere. Imprinted on that light is information about the gas giant's atmosphere, which yields clues about the properties of Jupiter's high-altitude haze above the cloud tops.

The view of the Hubble Advanced Camera for Surveys is filled by stars, part of NGC 6791, an old open star cluster in the Lyra constellation. The bright stars are roughly 13,300 light years distant. Two background galaxies, far beyond our own Milky Way, can be seen at upper left. More info here. (NASA, ESA, and L. Bedin, STScI) #
The Butterfly Nebula Nebula, NGC 6302, is one of the brightest and most extreme planetary nebulae known. What resemble dainty wings are actually roiling cauldrons of gas heated to more than 36,000 degrees Fahrenheit. The gas is tearing across space at more than 600,000 miles an hour. A dying star that was once about five times the mass of the Sun is at the center of this fury. It has ejected its envelope of gases and is now unleashing a stream of ultraviolet radiation that is making the cast-off material glow. NGC 6302 lies within our Milky Way galaxy, roughly 3,800 light-years away in the constellation Scorpius. The glowing gas is the star's outer layers, expelled over about 2,200 years. The "butterfly" stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Alpha Centauri. More info here. (NASA, ESA, and the Hubble SM4 ERO Team) #
Fine detail and exceptionally perfect spiral structure are apparent in this image of galaxy NGC 634. This spiral galaxy was discovered back in the nineteenth century by French astronomer Édouard Jean-Marie Stephan, but in 2008 it became a prime target for observations thanks to the violent demise of a white dwarf star. The type Ia supernova known as SN2008a was spotted in the galaxy and briefly rivalled the brilliance of its entire host galaxy but, despite the energy of the explosion, it can no longer be seen this Hubble image, which was taken around a year and a half later. Other, far more distant galaxies can be seen in the background as well in this image, which has an exposure time of nearly 3 hours. NGC 634 lies some 250 million light years away. More info here.

In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The burst of light from the bizarre star spread into space, reflecting off of surrounding shells of dust to reveal a spectacular set of images. The star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" around the star uncovered remarkable new features. These details provided astronomers with a CAT-scan-like probe of the three-dimensional structure of shells of dust surrounding an aging star. More info here. (NASA, ESA and H.E. Bond, STScI) #
At first glance, the scatter of pale dots on this NASA/ESA Hubble Space Telescope image might look like a snowstorm in the night sky. But almost every one of these delicate snowflakes is a distant galaxy in the cluster MACS J0717.5+3745 and each is home to billions of stars. This apparently placid scene also hides a storm of epic scale. This picture shows a region where three galaxy clusters are merging and releasing enormous amounts of energy in the form of X-rays. These distant objects are around 5.4 billion light-years from Earth, and were imaged during the Massive Cluster Survey, a project to study distant clusters of galaxies using Hubble. The amount of mass in this sea of galaxies is huge, and is great enough to visibly bend the fabric of spacetime. The strange distortion in the shapes of some of the galaxies in this picture, which appear stretched and bent as if they were looked at through a glass bottle, is a result of gravitational lensing, where the gravitational fields around massive objects bend light around them. Predicted by Einstein in his famous general theory of relativity, gravity's ability to distort light was first demonstrated in 1919 in a well-known experiment carried out by Sir Arthur Eddington, who led an expedition to the island of Principe, off the coast of Africa, to measure the apparent shift of a star when observed close to the edge of the Sun's disc during a solar eclipse.

An unusual, ghostly green blob of gas appears to float near a normal-looking spiral galaxy. The bizarre object, dubbed Hanny's Voorwerp (Hanny's Object in Dutch), is the only visible part of a 300,000-light-year-long streamer of gas stretching around the galaxy, called IC 2497. The greenish Voorwerp is visible because a searchlight beam of light from the galaxy's core illuminated it. This beam came from a quasar, a bright, energetic object that is powered by a black hole. The quasar may have turned off about 200,000 years ago. This Hubble view uncovers a pocket of star clusters, the yellowish-orange area at the tip of Hanny's Voorwerp. The star clusters are confined to an area that is a few thousand light-years wide. The youngest stars are a couple of million years old. The Voorwerp is the size of our Milky Way galaxy, and its bright green color is from glowing oxygen. Hubble also shows that gas flowing from IC 2497 may have instigated the star birth by compressing the gas in Hanny's Voorwerp. The galaxy is located about 650 million light-years from Earth. What appears to be a gaping hole in Hanny's Voorwerp actually may be a shadow cast by an object in the quasar's light path. The feature gives the illusion of a hole about 20,000 light-years wide. Hubble reveals sharp edges but no other changes in the gas around the apparent opening, suggesting that an object close to the quasar may have blocked some of the light and projected a shadow on the Voorwerp. This phenomenon is similar to a fly on a movie projector lens casting a shadow on a movie screen. More info here. (NASA, ESA, W. Keel, University of Alabama, and the Galaxy Zoo Team) #
The Horsehead Nebula, also known as Barnard 33, is a cold, dark cloud of gas and dust, silhouetted against the bright nebula, IC 434. The bright area at the top left edge is a young star still embedded in its nursery of gas and dust. But radiation from this hot star is eroding the stellar nursery. The top of the nebula also is being sculpted by radiation from a massive star located out of Hubble's field of view. Only by chance does the nebula roughly resemble the head of a horse. Its unusual shape was first discovered on a photographic plate in the late 1800s. More info here. (NASA, NOAO, ESA and The Hubble Heritage Team, STScI/AURA) #
The dancing light of the auroras on Saturn. Seen from space, an aurora appears as a ring of glowing gases circling a planet's polar region. Auroral displays are initiated when charged particles in space collide with a planet's magnetic field. The charged particles are accelerated to high energies and stream into the upper atmosphere. Collisions with the gases in the planet's atmosphere produce flashes of glowing energy in the form of visible, ultraviolet, and infrared light. Astronomers combined ultraviolet images of Saturn's southern polar region with visible-light images of the planet and its rings from both Hubble and the Cassini spacecraft to make this picture. The auroral display appears blue because of the glow of ultraviolet light. In reality, the aurora would appear red to an observer at Saturn because of the presence of glowing hydrogen in the atmosphere. This image was taken in January of 2004. More info here. (NASA, ESA, J. Clarke, Boston University, and Z. Leva, STScI) #
Dark clouds float in the fantasy-like landscape of the Carina Nebula, sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology). This detail is from a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission. More info here.(NASA, ESA, N. Smith, UC Berkeley, STScI/AURA) #
A delicate sphere of gas floats serenely in the depths of space. The pristine shell, or bubble, is the result of gas that is being shocked by the expanding blast wave from a supernova. Called SNR 0509-67.5 (or SNR 0509 for short), the bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud (LMC), a small galaxy about 160,000 light-years from Earth. Ripples in the shell's surface may be caused by either subtle variations in the density of the ambient interstellar gas, or possibly driven from the interior by pieces of the ejecta. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 11 million miles per hour (5,000 kilometers per second). Astronomers have concluded that the explosion was one of an especially energetic and bright variety of supernovae. Known as Type Ia, such supernova events are thought to result from a white dwarf star in a binary system that robs its partner of material, takes on much more mass than it is able to handle, and eventually explodes. Hubble's Advanced Camera for Surveys observed the supernova remnant on Oct. 28, 2006, with a filter that isolates light from glowing hydrogen seen in the expanding shell. These observations were then combined with visible-light images of the surrounding star field that were imaged with Hubble's Wide Field Camera 3 on Nov. 4, 2010. With an age of about 400 years as seen from Earth, the supernova might have been visible to southern hemisphere observers around the year 1600. However, there are no known records of a "new star" in the direction of the LMC near that time. A more recent supernova in the LMC, SN 1987A, did catch the eye of Earth viewers and continues to be studied with ground- and space-based telescopes, including Hubble. More info here.

A close view of spiral galaxy NGC 2841. A bright cusp of starlight marks the galaxy's center. Spiraling outward are dust lanes that are silhouetted against the population of whitish middle-aged stars. Much younger blue stars trace the spiral arms. Notably missing are pinkish emission nebulae indicative of new star birth. It is likely that the radiation and supersonic winds from fiery, super-hot, young blue stars cleared out the remaining gas (which glows pink), and hence shut down further star formation in the regions in which they were born. NGC 2841 currently has a relatively low star formation rate compared to other spirals that are ablaze with emission nebulae. NGC 2841 lies 46 million light-years away in the constellation of Ursa Major (The Great Bear). This image was taken in 2010 through four different filters on Hubble's Wide Field Camera 3. More info here. (NASA, ESA, STScI/AURA-ESA) #
This is a full-field image of the nearby dwarf galaxy NGC 4214. Episodes of star formation are revealed as the galaxy continues to form clusters of new stars from its interstellar gas and dust. This image reveals a sequence of steps in the formation and evolution of stars and star clusters, evident in the glowing gas surrounding bright stellar clusters. The young clusters of new stars appear within bright clumps of glowing gas. Each cloud glows because of the strong ultraviolet light emitted from the embedded young stars, which have formed within them due to the gravitational collapse of the gas. These hot stars also eject fast "stellar winds" moving at millions of miles per hour (thousands of kilometers per second), which plow into the surrounding gas. The radiation and wind from the young stars literally blow bubbles in the gas. The main object near the center of the galaxy is a cluster of hundreds of massive blue stars, each more than 10,000 times brighter than our Sun. A vast heart-shaped bubble, inflated by the combined stellar winds and radiation pressure, surrounds the cluster. The bubble will increase in size as the most massive stars in the center reach the ends of their lives and explode as supernovae. This dwarf galaxy resides 10 million light-years away in the constellation Canes Venatici. More info here. (NASA, ESA, and the Hubble Heritage STScI/AURA - ESA/Hubble Collaboration) #
This image of ESO 77-14 is a stunning snapshot of a celestial dance performed by a pair of similar sized galaxies. Two clear signatures of the gravitational tug of war between the galaxies are the bridge of material that connects them and the disruption of their main bodies. The galaxy on the right has a long, bluish arm while its companion has a shorter, redder arm. This interacting pair is in the constellation of Indus, the Indian, some 550 million light-years away from Earth. The dust lanes between the two galaxy centers show the extent of the distortion to the originally flat disks that have been pulled into three-dimensional shapes. More info here.

This gaseous cloud named IC 4593 is a planetary nebula. Planetary nebulae are created when stars in the last stages of life cast off their outer layers of material into space. Ultraviolet light from the remnant star makes the material glow. Planetary nebulae last for only 10,000 years, a fleeting episode in the 10-billion-year lifespan of Sun-like stars. Over thousands of years, the clouds of gas expand away and the nebulae become larger. Energetic ultraviolet light from the star penetrates more deeply into the gas, causing the hydrogen and oxygen to glow more prominently. In older nebulae, such as IC 4593, hydrogen and oxygen appear more extended in these regions, and red knots of nitrogen are still visible. IC 4593 lies some about 7,000 light-years from Earth, in the northern constellation Hercules. More info here. (NASA, ESA, and The Hubble Heritage Team, STScI/AURA) #
The high concentration of stars within globular clusters, like Messier 12, shown here, makes them beautiful photographic targets. But the cramped living quarters in these clusters also makes them home to exotic binary star systems where two stars are locked in tight orbits around each other and matter from one is gobbled up by its companion, releasing X-rays. It is thought that such X-ray binaries form from very close encounters between stars in crowded regions, such as globular clusters, and even though Messier 12 is fairly diffuse by globular cluster standards, such X-ray sources have been spotted there. Astronomers have also discovered that Messier 12 is home to far fewer low-mass stars than was previously expected. In a recent study, astronomers used the European Southern Observatory's Very Large Telescope at Cerro Paranal, Chile, to measure the brightness and colours of more than 16,000 of the cluster's 200 000 stars. They speculate that nearly one million low-mass stars have been ripped away from Messier 12 as the globular has passed through the densest regions of the Milky Way during its orbit around the galactic center. It seems that the serenity of this view of Messier 12 is misleading and the object has had a violent and disturbed past. Messier 12 lies about 23,000 light-years away in the constellation of Ophiuchus (The Serpent Bearer). More info here. (ESA/Hubble & NASA) #
A long-exposure image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble's cameras, paired with considerably long exposures, made it possible to observe these faint details. NGC 4911 and other spirals near the center of the cluster are being transformed by the gravitational tug of their neighbors. In the case of NGC 4911, wispy arcs of the galaxy's outer spiral arms are being pulled and distorted by forces from a companion galaxy (NGC 4911A), to the upper right. This natural-color Hubble image, which combines data obtained in 2006, 2007, and 2009 from the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, required 28 hours of exposure time.

The Antennae galaxies, a pair of merging spiral galaxies. During the course of the collision, billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters. The two galaxies started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies. Nearly half of the faint objects in the Antennae image are young clusters containing tens of thousands of stars. The orange blobs to the left and right of image center are the two cores of the original galaxies and consist mainly of old stars criss-crossed by filaments of dust, which appears brown in the image. The two galaxies are dotted with brilliant blue star-forming regions surrounded by glowing hydrogen gas, appearing in the image in pink. The Antennae galaxies take their name from the long antenna-like "arms" extending far out from the nuclei of the two galaxies, best seen by ground-based telescopes. More info here.

Four and a half billion light-years away in the constellation Virgo, scores of galaxies in a cluster known as MACS 1206 have been drawn together by their mutual gravitational pull. Gravity from the cluster's immense mass bends the space around it, causing the images of more distant galaxies directly behind the cluster (that are within our line of sight) to be warped and cast into arc-like smears of light. The orange streak to the right of the image center is one such example of an optically distorted galaxy that resides millions of light-years behind MACS 1206. The circular pattern of smaller galaxy pieces is more evidence of gravitational lensing. The central object in the cluster is a giant elliptical galaxy plump with billions of old, reddish suns, surrounded by a thinner halo of stars. Disk-shaped spiral galaxies appear, both edge- and face-on, showing a defined structure of arms encircling their central bulges. The bluer galaxies have stars actively forming within them and, consequently, host groups of young blue stars that contribute to their overall hue. In contrast, red galaxies - especially those elliptical galaxies like the center one - are more stable in their behavior, with very few little recent star formation. More info here. (NASA, ESA, M. Postman, the CLASH Team, STScI/AURA) #
The little-known nebula IRAS 05437+2502 billows out among the bright stars and dark dust clouds that surround it in this striking image. It is located in the constellation of Taurus (the Bull), close to the central plane of our Milky Way galaxy. Unlike many of Hubble's targets, this object has not been studied in detail and its exact nature is unclear. At first glance it appears to be a small, rather isolated, region of star formation and one might assume that the effects of fierce ultraviolet radiation from bright young stars probably were the cause of the eye-catching shapes of the gas. However, the bright boomerang-shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp-edged bright arc. Such a reckless star would have been ejected from the distant young cluster where it was born and would travel at 200,000 km/hour or more through the nebula. More info here. (ESA/Hubble, R. Sahai and NASA) #
The outstretched "wings" of the this bipolar star-forming region called Sharpless 2-106 record the contrasting imprint of heat and motion against the backdrop of a colder medium. Sharpless 2-106, Sh2-106 or S106 for short, lies nearly 2,000 light-years from us. The nebula measures several light-years in length. It appears in a relatively isolated region of the Milky Way galaxy. A massive, young star, IRS 4 (Infrared Source 4), is responsible for the furious activity we see in the nebula. Twin lobes of super-hot gas, glowing blue in this image, stretch outward from the central star.

More than 12 billion years of cosmic history are shown in this unprecedented, panoramic, full-color view of thousands of galaxies in various stages of assembly. The view covers a portion of the southern field of a large galaxy census called the Great Observatories Origins Deep Survey (GOODS), a deep-sky study by several observatories to trace the formation and evolution of galaxies. The image shows a rich tapestry of thousands galaxies stretching back through most of the universe's history. The closest galaxies seen in the foreground emitted their observed light about a billion years ago. The farthest galaxies, a few of the very faint red specks, are seen as they appeared more than 13 billion years ago, or roughly 650 million years after the Big Bang. From top to bottom, this mosaic spans a tiny slice of space that is equal to 1/6 of the full moon, 5 arcminutes -- or, if you held a penny up to the sky at arms length, and looked at it edge-on, the thickness of the penny would nearly cover the whole vista. This Hubble image is one of several, including the Ultra Deep Field, which peer into seemingly empty space, leaving the camera shutter open for hours, and reveal that billions of galaxies made up of billions of stars fill our skies in every direction as far as we can possibly see, separated by almost unimaginable distance and time, yet still reachable, visible as an image of their long-ago selves. Take a good look at the image above, nearly every speck of color is a galaxy. Seeing that, and thinking of the recent explosion in discoveries of planets outside our own solar system (over 700 found to date), the unbelievably vast scale of possible worlds in the Universe becomes apparent - out there, all around us. Merry Christmas, thanks for spending some time with these images, and many thanks to all the scientific teams responsible. Here's hoping for even more amazing discoveries in 2012! - Alan More infohere.

This view of the lower front and underbelly areas of NASA's Mars rover Curiosity combines nine images taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Curiosity's work on Mars, on September 9, 2012. Curiosity's front Hazard-Avoidance cameras appear as a set of four blue eyes at the top center of the portrait. Fine-grain Martian dust can be seen adhering to the wheels, which are about 16 inches (40 centimeters) wide and 20 inches (50 centimeters) in diameter. The bottom of the rover is about 26 inches (66 centimeters) above the ground. On the horizon at the right is a portion of Mount Sharp, with dark dunes at its base. The camera is in the turret of tools at the end of Curiosity's robotic arm. (NASA/JPL-Caltech/Malin Space Science Systems) #
On Sol 32, September 7, 2012, the Curiosity rover used a camera located on its arm to obtain this self portrait. The image of the top of Curiosity's Remote Sensing Mast, showing the Mastcam and Chemcam cameras, was acquired by the Mars Hand Lens Imager (MAHLI). The angle of the frame reflects the position of the MAHLI camera on the arm when the image was taken. (NASA/JPL-Caltech/Malin Space Science Systems) #
The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser to examine side-by-side points in a target patch of soil, leaving the marks apparent in this before-and-after comparison. The two images were taken by ChemCam's Remote Micro-Imager from a distance of about 11.5 feet (3.5 meters). The diameter of the circular field of view is about 3.1 inches (7.9 centimeters). Researchers used ChemCam to study this soil target, named "Beechey," during the 19th Martian day, or sol, of Curiosity's mission, August 25, 2012. (NASA/JPL-Caltech/LANL/CNES/IRAP/LPGN/CNRS) #
On September 8, 2012, Curiosity's Mars Hand Lens Imager (MAHLI) took this detailed image of Martian soil. The patch of ground shown is about 34 inches (86 centimeters) across. The size of the largest pebble, near the top of the image, is about 3 inches (8 centimeters). Notice that the ground immediately around that pebble has less dust visible (more gravel exposed) than in other parts of the image. The presence of the pebble may have affected the wind in a way that preferentially removes dust from the surface around it. (NASA/JPL-Caltech/Malin Space Science Systems) #
The penny in this image is part of a camera calibration target on NASA's Mars rover Curiosity. The MAHLI camera on the rover took this and other images of the MAHLI calibration target on September 9, 2012. The penny is a nod to geologists' tradition of placing a coin or other object of known scale as a size reference in close-up photographs of rocks, and it gives the public a familiar object for perceiving size easily when it will be viewed by MAHLI on Mars. The specific coin, provided by MAHLI's principal investigator, Ken Edgett, is a 1909 "VDB" penny. That was the first year Lincoln pennies were minted and the centennial of Abraham Lincoln's birth. The VDB refers to the initials of the coin's designer, Victor D. Brenner, which are on the reverse side. The calibration target for the Mars Hand Lens Imager (MAHLI) instrument also includes a "Joe the Martian" character, color references, a metric bar graphic, and a stair-step pattern for depth calibration.

The left eye of the Mast Camera (Mastcam) on NASA's Mars rover Curiosity took this image of the MAHLI camera on the rover's arm, on Mars, on September 5, 2012. The image shows that MAHLI has a thin film or coating of Martian dust on it. This dust accumulated during Curiosity's final descent to the Martian surface, as the Mars Science Laboratory spacecraft's descent stage (or sky crane) engines were disrupting the surface nearby. The reddish circle near the center of the Mastcam Sol 30 image is the window of MAHLI's dust cover, with a diameter a little less than a soda can's diameter. The mechanism at the right in this image is Curiosity's dust removal tool, a motorized wire brush. (NASA/JPL-Caltech/MSSS) #

They are among the most arresting images of an asteroid ever seen.
Nasa today released two new images taken from its Dawn spacecraft as it left the giant Vesta asteroid.
The first set of images is a color-coded relief map of Vesta's northern hemisphere, from the pole to the equator.
Scroll down for video
Nasa's Dawn mission has revealed the topography of the northern and southern hemispheres of the giant asteroid Vesta.
Vesta was discovered in 1807, the fourth asteroid to be identified in the great belt of rocky debris orbiting between Mars and Jupiter.
At the time, its great scale meant it was designated as another planet but it later lost this status as researchers learnt more about the diversity of objects in the Solar System.
It incorporates images taken just as Dawn began to creep over the high northern latitudes, which were dark when Dawn arrived in July 2011.
The other image is a black-and-white mosaic that shows a full view of the giant asteroid, created by synthesizing some of Dawn's best images.
'Dawn has peeled back the veil on some of the mysteries surrounding Vesta, but we're still working hard on more analysis,' said Christopher Russell, Dawn's principal investigator at UCLA.
'So while Vesta is now out of sight, it will not be out of mind.'
The images mark the end of Dawn's year-long encounter with the 330mile-wide asteroid Vesta, making the mission the first to enter orbit around a main-belt asteroid.
The main asteroid belt lies between the orbits of Mars and Jupiter, 117million miles from Earth.
The asteroid looks like a punctured football, the result of a colossal collision sometime in its past that knocked off its south polar region.
Dawn will now depart for its second destination, the dwarf planet Ceres.
This will make it the first spacecraft to orbit two solar system destinations beyond Earth.

The south pole of Titan which is 3,200 miles (5,150 km) across is near the center of the view. The formation of the vortex at Titan's south pole may be related to the coming southern winter and the start of what will be a south polar hood. These new, more detailed images are only possible because of Cassini's newly inclined orbits, which are the next phase of Cassini Solstice Mission.

A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA's Cassini spacecraft, on May 6, 2012. As the seasons have changed in the Saturnian system, and spring has come to the north and autumn to the south, the azure blue in the northern Saturnian hemisphere that greeted Cassini upon its arrival in 2004 is now fading. The southern hemisphere, in its approach to winter, is taking on a bluish hue. This change is likely due to the reduced intensity of ultraviolet light and the haze it produces in the hemisphere approaching winter, and the increasing intensity of ultraviolet light and haze production in the hemisphere approaching summer.

Nasa reveals massive halo of hot gas that envelops our universe
It is an astonishing reminder of just how large the universe is. Nasa today revealed this incredible image showing our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years.
The estimated mass of the halo is comparable to the mass of all the stars in the galaxy.
This artist's illustration shows an enormous halo of hot gas (in blue) around the Milky Way galaxy
THE MISSING BARYONS
Baryons are particles, such as protons and neutrons, that make up more than 99.9 percent of the mass of atoms found in the cosmos.
Measurements of extremely distant gas halos and galaxies indicate the baryonic matter present when the universe was only a few billion years old represented about one-sixth the mass and density of the existing unobservable, or dark, matter.
In the current epoch, about 10 billion years later, a census of the baryons present in stars and gas in our galaxy and nearby galaxies shows at least half the baryons are unaccounted for
Astronomers have used NASA's Chandra X-ray Observatory to estimate the size.
If the size and mass of this gas halo is confirmed, it also could be an explanation for what is known as the 'missing baryon' problem for the galaxy.
Baryons are particles, such as protons and neutrons, that make up more than 99.9 percent of the mass of atoms found in the cosmos.
Measurements of extremely distant gas halos and galaxies indicate the baryonic matter present when the universe was only a few billion years old represented about one-sixth the mass and density of the existing unobservable, or dark, matter.
In the current epoch, about 10 billion years later, a census of the baryons present in stars and gas in our galaxy and nearby galaxies shows at least half the baryons are unaccounted for.
In a recent study, a team of five astronomers used data from Chandra, the European Space Agency's XMM-Newton space observatory and Japan's Suzaku satellite to set limits on the temperature, extent and mass of the hot gas halo.
Chandra observed eight bright X-ray sources located far beyond the galaxy at distances of hundreds of millions of light-years.
The data revealed X-rays from these distant sources are absorbed selectively by oxygen ions in the vicinity of the galaxy.
The scientists determined the temperature of the absorbing halo is between 1 million and 2.5 million kelvins, or a few hundred times hotter than the surface of the sun.
Other studies have shown that the Milky Way and other galaxies are embedded in warm gas with temperatures between 100,000 and 1 million kelvins.
Studies have indicated the presence of a hotter gas with a temperature greater than 1 million kelvins.
This new research provides evidence the hot gas halo enveloping the Milky Way is much more massive than the warm gas halo.
'We know the gas is around the galaxy, and we know how hot it is,' said Anjali Gupta, lead author of The Astrophysical Journal paper describing the research.
The Milky Way galaxy. Researchers now believe a vast gas cloud covers our galaxy. 'The big question is, how large is the halo, and how massive is it?' To begin to answer this question, the authors supplemented Chandra data on the amount of absorption produced by the oxygen ions with XMM-Newton and Suzaku data on the X-rays emitted by the gas halo.
They concluded that the mass of the gas is equivalent to the mass in more than 10 billion suns, perhaps as large as 60 billion suns.
'Our work shows that, for reasonable values of parameters and with reasonable assumptions, the Chandra observations imply a huge reservoir of hot gas around the Milky Way,' said co-author Smita Mathur of Ohio State University in Columbus.
'It may extend for a few hundred thousand light-years around the Milky Way or it may extend farther into the surrounding local group of galaxies. 'Either way, its mass appears to be very large.'The estimated mass depends on factors such as the amount of oxygen relative to hydrogen, which is the dominant element in the gas.
Nevertheless, the estimation represents an important step in solving the case of the missing baryons, a mystery that has puzzled astronomers for more than a decade. Although there are uncertainties, the work by Gupta and colleagues provides the best evidence yet that the galaxy's missing baryons have been hiding in a halo of million-kelvin gas that envelopes the galaxy. The estimated density of this halo is so low that similar halos around other galaxies would have escaped detection.
This image, taken by the Hubble Space Telescope, shows the five known moons orbiting the distant, icy dwarf planet Pluto. The green circle marks the newly discovered moon, designated S/2012 (134340) 1, or P5, as photographed by Hubble's Wide Field Camera 3 on 7 July 2012. The moon is estimated to be 10 to 25 kilometers across. It is in a 95,000 kilometer diameter circular orbit around Pluto that is assumed to be aligned in the same plane as the other satellites in the system. The darker stripe in the center of the image is because the picture is constructed from a long exposure designed to capture the comparatively faint satellites of Nix, Hydra, P4 and S/2012 (134340) 1, and a shorter exposure to capture Pluto and Charon, which are much brighter. NASA's New Horizons probe, which will rendezvous with Pluto in July of 2015, was launched in 2006 -- back then, Pluto only had three known moons. (Mr. Showalter/AFP/Getty Images
The galaxy is so far away - the ray of light journeyed for 13.2 billion years to get bring us this image - that by rights, we should not be able to see it.
But thanks to a universe-wide trick of the light, we have been able to glimpse back at a galaxy so far, far away, and from such a long, long time ago, that its light shone out when the universe was just 500 million years old - and still shrouded in blackness.
Nasa's Hubble satellite should not have been able to see it.
But as the galaxy passed behind a giant cluster of galaxies, the cluster acted like a giant lens magnifying the light by 15 times - and bringing us this tiny glimpse of the universe in its earliest years.
The image was released today - just as the finishing touches are put on to the mirrors of the James Webb Space Telescope, which will launch later this decade to bring back even more distant images.
It was probably the widest-observed event in human history - but it was also the loneliest of deaths.
The furthest object we have ever seen: Hubble peers into the blackness and picks up the magnified rays of the MACS J1149+2223 galaxy
In the big image, on the left the many galaxies of a massive cluster called MACS J1149+2223 dominate the scene.
Gravitational lensing by the giant cluster brightened the light from the newfound galaxy, known as MACS 1149-JD, some 15 times
At upper right, a partial zoom-in shows MACS 1149-JD in more detail, and a deeper zoom appears to the lower right.
The far-off galaxy existed within an important era when the universe began to transit from the so-called cosmic dark ages.
During this period, the universe went from a dark, starless expanse to a recognizable cosmos full of galaxies. The discovery of the faint, small galaxy opens a window onto the deepest, most remote epochs of cosmic history.
'This galaxy is the most distant object we have ever observed with high confidence,' said Wei Zheng, a principal research scientist in the department of physics and astronomy at Johns Hopkins University in Baltimore.
'Future work involving this galaxy, as well as others like it that we hope to find, will allow us to study the universe's earliest objects and how the dark ages ended.'
No light pollution here: The Hubble floats above our atmosphere, surveying the universe
Light from the primordial galaxy traveled approximately 13.2 billion light-years before reaching NASA's telescopes. In other words, the starlight snagged by Hubble and Spitzer left the galaxy when the universe was just 3.6 percent of its present age.
Technically speaking, the galaxy has a redshift, or 'z',of 9.6.
The term redshift refers to how much an object's light has shifted into longer wavelengths as a result of the expansion of the universe. Astronomers use redshift to describe cosmic distances.
Unlike previous detections of galaxy candidates in this age range, which were only glimpsed in a single color, or waveband, this newfound galaxy has been seen in five different wavebands.
As part of the Cluster Lensing And Supernova Survey with Hubble Program, the Hubble Space Telescope registered the newly described, far-flung galaxy in four visible and infrared wavelength bands.
Spitzer measured it in a fifth, longer-wavelength infrared band, placing the discovery on firmer ground.
Objects at these extreme distances are mostly beyond the detection sensitivity of today's largest telescopes. To catch sight of these early, distant galaxies, astronomers rely on gravitational lensing.
In this phenomenon, predicted by Albert Einstein a century ago, the gravity of foreground objects warps and magnifies the light from background objects.
Based on the Hubble and Spitzer observations, astronomers think the distant galaxy was less than 200 million years old when it was viewed. It also is small and compact, containing only about 1 percent of the Milky Way's mass.
According to leading cosmological theories, the first galaxies indeed should have started out tiny. They then progressively merged, eventually accumulating into the sizable galaxies of the more modern universe.
These first galaxies likely played the dominant role in the epoch of reionization, the event that signaled the demise of the universe's dark ages.
This epoch began about 400,000 years after the Big Bang when neutral hydrogen gas formed from cooling particles.
Other images from Hubble: Over 60,000 light-years across, M51's spiral arms and dust lanes clearly sweep in front of its companion galaxy (right)
One of the most famous images of modern times: This image, taken with the Hubble Space Telescope in 1995, shows evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. The giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars
The first luminous stars and their host galaxies emerged a few hundred million years later.
The bizarre spiral structure was spotted by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, and is believed to be a hidden companion star orbiting the star.
WHAT IS IT?
The old red giant star R Sculptoris sits at its centre, ejecting dust and gas every 10,000 to 50,0000 years to form a shell of surrounding material.
Spherical shells have been seen around red giants before, but this kind of spiral is unique.
It is believed is was caused by a previously unseen companion star carving through the material as it orbits.
At 16,000ft up in the Chilean Andes the Atacama Large Millimeter/submillimeter Array (ALMA) is also the highest such machine on Earth.
The Atacama desert was chosen for its dryness and clarity.
The feature in the gas around the old star has never been seen before and is probably caused by a hidden companion star orbiting it.
The data reveals the shell around the star - which shows up as the outer circular ring - as well as a very clear spiral structure in the inner material.
The astronomers were also surprised to find far more matter than expected had been ejected by the red giant which is in the last phase of its life as is expanding as its temperature soars.
Professor Matthias Maercker, of Bonn University in Germany, said: 'We’ve seen shells around this kind of star before but this is the first time we’ve ever seen a spiral of material coming out from a star together with a surrounding shell.'
Red giants like R Sculptoris are major contributors to the dust and gas that provide the bulk of the raw materials for the formation of future generations of stars, planetary systems and subsequently for life.
The shot published in Nature is a glimpse of the potential of ALMA that will not even come into full operation until next year.
Study co-author Dr Wouter Vlemmings, of Chalmers University of Technology in Gothenburg, Sweden, said: 'When we observed the star with ALMA not even half its antennas were in place.
'It’s really exciting to imagine what the full ALMA array will be able to do once it’s completed in 2013.'
Late in their lives stars up to eight times bigger than the Sun become red giants and lose a large amount of their mass in a dense stellar wind..
This chart shows the location of the red giant star R Sculptoris in the constellation of Sculptor (The Sculptor). The star itself is marked with a red circle.
ALMA operates at higher sensititivity and higher resolution than any previous ‘sub-millimetre’ radio telescope - and should allow us to see the formation of new solar systems.
ALMA can see through cold clouds of dust that ‘block the view’ of traditional infrared/visible light telescopes and as more antennae come online its images will get sharper.
It sits in the Chajnantor plateau 1500 km north of Santiago and is 4Oft tall.
During this stage they also periodically undergo thermal pulses - short-lived phases of explosive helium burning in a shell around the stellar core.
A thermal pulse leads to material being blown off the surface of the star at a much higher rate resulting in the formation of a large shell of dust and gas around the star. After the pulse the rate at which the star loses mass falls again to its normal value,
Thermal pulses occur about every 10,000 to 50,000 years and last only a few hundred years.
The new observations of R Sculptoris show it suffered such an event roughly 1,800 years ago that lasted for about 200 years.
The companion star shaped the wind from R Sculptoris into a spiral structure.
Prof Maercker said: 'By taking advantage of the power of ALMA to see fine details we can understand much better what happens to the star before, during and after the thermal pulse by studying how the shell and the spiral structure are shaped.
'We always expected ALMA to provide us with a new view of the Universe but to be discovering unexpected new things already with one of the first sets of observations is truly exciting.'
The findings show how ALMA is already giving new insight into what’s happening in these stars and what might happen to the Sun a few billion years from now.

'They also give us a hint of what our own star’s far future might be like.'
This wide-field image shows the patch of sky around the red giant variable star R Sculptoris. The view was created from photographs forming part of the Digitized Sky Survey 2.
The death throes of dying stars have been captured in unprecedented detail by NASA's Chandra X-ray satellite observatory.
the images are the culmination of work by two dozen astronomers to image a set of dying stars in the neighborhood of the Sun.
The resulting X-ray images of these dying stars—called planetary nebulae—are shedding light on the violent 'end game' of a Sun-like star's life.
Four planetary nebulae are shoFour planetary nebulae are shown here from the first systematic survey of these dying, Sun-like stars in the solar neighborhood using the Chandra X-Ray Observatory. X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue. The nebulae are NGC 6543, also known as the Cat's Eye, NGC 7662, NGC 7009 and NGC 6826.wn here from the first systematic survey of these dying, Sun-like stars in the solar neighborhood using the Chandra X-Ray Observatory.
A planetary nebula is a dying star that has cast off its outer layers.
The newly exposed, hot core of the star (which will eventually become a 'white dwarf' star) illuminates these ejected layers, while the core's fast winds sculpt the material into a variety of shapes.
The resulting dazzling objects, bearing names like Cat's Eye, Lemon Slice and Blue Snowball, are favorite targets of optical and near-infrared telescopes.
The research team, led by Joel Kastner from Rochester Institute of Technology, won seven days of observing time with Chandra in 2011 to survey and image nearly two dozen relatively nearby planetary nebulae, resulting in the most comprehensive X-ray survey to date for such objects.
The same team recently won an eight-day time award with Chandra to continue its observing program, and will begin collecting new X-ray data later this year.

'Planetary nebulae have provided astrophysicists with dying star 'laboratories' for more than a century,' Kastner says.
'They provide test beds for theories of stellar evolution and give us insight into the origin of heavy elements in the universe and on Earth.
'Yet we still don't fully understand why they take on such a dazzling variety of shapes.'
The widespread debate among astrophysicists concerning the planetary nebula shaping process led Kastner and postdoctoral fellow Rodolfo Montez Jr. to organize their colleagues to request a large allocation of X-ray satellite observing time to investigate the processes of stellar death and wind collisions in X-rays.
'An X-ray survey of this kind is completely uncharted territory in the planetary nebula world,' Kastner adds.
'Astronomers working in this area agreed that we need large quantities of time to look at as many planetary nebulae as possible, specifically with Chandra.'
His team is using X-ray imaging to look 'under the hood' of planetary nebulae.
X-rays cut through the illuminated gas and dust, allowing astronomers to investigate the last tens of thousands of years of history of the dying star that threw off its outer sheaths.
The nebulae NGC 7009 from the first systematic survey of these dying, Sun-like stars in the solar neighborhood using the Chandra X-Ray Observatory.
'With Chandra's exceptional 'X-ray vision,' we can detect the million-degree plasma inside the discarded shells and probe the energies of the stellar winds that shape them,' Kastner says.
In the initial phase of the project, the team collected data for 35 planetary nebulae—21 previously unobserved and 14 pulled from Chandra archival data—all within roughly 5,000 light years of the Sun.
The recent award will bump the study to a total of 59 objects from among the roughly 120 planetary nebulae identified within this distance.
'Because they all just happen to lie relatively nearby, we think this group of objects is fairly representative of planetary nebulae in general,' Kastner says.
The findings will give theorists material to refine models describing mechanisms that shape planetary nebulae, especially the potential influence of a stellar or even a planetary companion to the dying star.
The Chandra survey data shows that most planetary nebulae with diffuse X-ray emission have sharp-rimmed shells that were ejected less than 5,000 years ago; these compact inner shells are surrounded by fainter halos of material ejected tens of thousands of years earlier.
Nordic Type “Tall White” aliens who are reported to have life-spans of approximately 600-700 human years
Actual KGB file photo of crashed UFO in Sverdlovsk, Russia in March of 1969. Note the “fusion” of the AGC’s hull with the ground which illustrates the sophisticated anti-gravity, phase shifting quality of the craft’s composition and anything it impacts. This is what a few survivors of the Philadelphia experiment remarked about and stated that some deck hands fused into the ships metal and died in that state shortly after.
Recently there have been well founded rumors that the USG is now in the process of setting up an official Office for Exopolitics and considering several esteemed individuals from which to choose a director to run this new office.
Exopolitics is the official, public admission by any government that the earth is being visited by extra-terrestrial or inter-stellar alien entities and a declaration that such matters will be addressed in appropriate terms.
Exopolitics encompasses all official governmental efforts to deal with the implications of the existence of extraterrestrial or extra-stellar life and its visitation or presence on planet earth after they have publicly confirmed such.
It is difficult to fully imagine the volcanic implications of such a complete disclosure, but it is fair to assume that it can and will affect almost every single area of contemporary human society and all public institutions including all governmental agencies as well as non-governmental organizations (NGOs).
And some insiders have stated that the SSG has had its own internal but secret Department of Exopolitics consisting of a committee of twelve known as Majestic 12, MJ-12 or referred to as “Majesty 12″ by some. And some reports have suggested that there has been a deep internal split in this group, with younger members pushing hard for complete USG public disclosure followed by the setting up of an official USG Department of Exopolitics.
So far the only retired public officials who have come forth and publicly stated that UFOs are real and alien creatures are associated with them publicly are Paul Hellyer, former Canadian Minister of defense Paul Hellyer and former Governor of Arizona Fife Symington.
Paul Hellyer was featured in this remarkable public youtube video.
One of the US Astronauts Gordon Cooper has gone public about what he saw many years ago.
Astronaut Buzz Aldrin also has gone public that UFOs and aliens are real:
During a recent interview (2) with former US Astronaut Edgar Mitchell published on Bloomberg on July 16, 2013, Mitchell stated:
In 2010 a public hearing was held at the Press Club in Washington DC by Steven Greer, MD’s Disclosure Project.
Dr. Steven Greer and the Disclosure Project.
Dr. Steven Greer, an emergency room Physician that is well respected has organized the Disclosure Project in which over 100 highly credible former US military and DOD contractors have come forward and stated public on several occasions first hand direct knowledge of UFO’s, alien visitation and extreme USG efforts to keep such knowledge secret and from the American taxpayer. And despite the fact that these disclosures are considered a serious breach of security agreements, nothing has been done to prosecute any these esteemed individuals who have been willing to come forward.
In fact Dr. Greer has contacted numerous Senators and Congress members repeatedly and appeared to have gained clear support for public congressional hearing of ETs and UFOs and excessive USG secrecy about such. So far all such “support” has seemed to just evaporate.
Dr. Greer’s recent efforts earlier this year involved the invitation of several Congress persons to moderate his Disclosure Project Hearings in Washington DC with the hope that this would break the cycle of denial and lead to a public disclosure of the truth about UFOs, ET’s and alien visitation.
I am happy to report that it does appear that all the magnificent work of Dr. Greer is now starting to pay off, however there are many other esteemed individuals who have been working in the background who are also helping to bring full USG disclosure about.
Deep inside the Vatican, Exopolitics has been a concern for a number of years.
Esteemed former Jesuit Malachi Martin before his death had claimed that a faction within the Vatican had gone “luciferian” and were conducting black masses in the basement of the Vatican. He also expressed to friends that it was dangerous for anyone involved inside the Vatican to disclose such things.

The energy released by these earliest galaxies is thought to have caused the neutral hydrogen strewn throughout the universe to ionize, or lose an electron, a state that the gas has remained in since that time.
'In essence, during the epoch of reionization, the lights came on in the universe,' said paper co-author Leonidas Moustakas, a research scientist at NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena.
Astronomers plan to study the rise of the first stars and galaxies and the epoch of reionization with the successor to both Hubble and Spitzer, NASA's James Webb Telescope, which is scheduled for launch in 2018. The newly described distant galaxy will likely be a prime target.
Astronomers successfully measure the radius of a black hole
In astronomy, the point of no return is known as a black hole - a region in space where the pull of gravity is so strong that nothing - not even light - can escape.
Now, an international team, led by researchers at MIT’s Haystack Observatory, has for the first time measured the radius of a black hole at the center of a distant galaxy - the closest distance at which matter can approach before being irretrievably pulled into the black hole.
The scientists linked together radio dishes in Hawaii, Arizona and California to create a telescope array called the 'Event Horizon Telescope' (EHT) that can see details 2,000 times finer than what is visible to the Hubble Space Telescope.
Galaxy M87: This image, created using computer models, shows how the extreme gravity of the black hole in M87 distorts the appearance of the jet near the event horizon - part of the radiation from the jet is bent by gravity into a ring that is known as the 'shadow' of the black hole
The radio dishes were trained on M87, a galaxy some 50 million light years from the Milky Way, which harbors a black hole six billion times more massive than our sun.
Using this array, the team observed the glow of matter near the edge of this black hole ' a region known as the 'event horizon'.
Black holes can be billions of times more massive than our sun and reside at the heart of most galaxies.
Such supermassive black holes are so powerful that activity at their boundaries can ripple throughout their host galaxies.
'Once objects fall through the event horizon, they’re lost forever,' said Shep Doeleman, assistant director at the MIT Haystack Observatory and research associate at the Smithsonian Astrophysical Observatory.
'It’s an exit door from our universe. You walk through that door, you’re not coming back.'
Supermassive black holes are the most extreme objects predicted by Albert Einstein’s theory of gravity - where, according to Doeleman, 'gravity completely goes haywire and crushes an enormous mass into an incredibly close space.'
At the edge of a black hole, the gravitational force is so strong that it pulls in everything from its surroundings. However, not everything can cross the event horizon to squeeze into a black hole. The result is a 'cosmic traffic jam' in which gas and dust build up, creating a flat pancake of matter known as an accretion disk.
Scientists have discovered a huge black hole lurking near the centre of our own galaxy thanks to a rare phenomenon which broadcast its presence with a torrent of high-energy X-rays.
Nasa's Swift satellite detected the rising surge of X-rays, produced by a rare X-ray nova, last month and say it is evidence of a black hole that is part of a binary system near the Milky Way's core.
'Bright X-ray novae are so rare that they're essentially once-a-mission events and this is the first one Swift has seen,' said Neil Gehrels, the mission's principal investigator.
'This is really something we've been waiting for.'

An X-ray nova is a short-lived X-ray source that appears suddenly, reaches its emission peak in a few days and then fades out over a period of months.
The outburst arises when a torrent of stored gas suddenly rushes toward one an incredibly dense and compact object, either a neutron star or a black hole. The rapidly brightening source triggered Swift's Burst Alert Telescope twice on the morning of September 16, and once again the next day.
Named Swift J1745-26 after the coordinates of its sky position, the nova is located a few degrees from the centre of our galaxy toward the constellation Sagittarius.
While astronomers do not know its precise distance, they think the object resides about 20,000 to 30,000 light-years away in the galaxy's inner region.
WHAT IS A BLACK HOLE?
A black hole is a region of space-time where gravity prevents anything, including light, from escaping.
The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole.
Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called 'black' because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.
Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.
Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings.
By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may form.
There is general consensus that supermassive black holes exist in the centres of most galaxies.
Ground-based observatories detected infrared and radio emissions, but thick clouds of obscuring dust have prevented astronomers from catching Swift J1745-26 in visible light.
The nova peaked in hard X-rays - energies above 10,000 electron volts, or several thousand times that of visible light - on September 18, when it reached an intensity equivalent to that of the famous Crab Nebula
That nebula is a supernova remnant that serves as a calibration target for high-energy observatories and is considered one of the brightest sources beyond the solar system at these energies.
Even as it dimmed at higher energies, the nova brightened in the lower-energy, or softer, emissions detected by Swift's X-ray Telescope, a behavior typical of X-ray novae.
By Wednesday, Swift J1745-26 was 30 times brighter in soft X-rays than when it was discovered and it continued to brighten.
'The pattern we're seeing is observed in X-ray novae where the central object is a black hole. Once the X-rays fade away, we hope to measure its mass and confirm its black hole status,' said Boris Sbarufatti, an astrophysicist at Brera Observatory in Milan, who currently is working with other Swift team members at Penn state.
The black hole must be a member of a low-mass X-ray binary (LMXB) system, which includes a normal, sun-like star. A stream of gas flows from the normal star and enters into a storage disk around the black hole. In most LMXBs, the gas in the disk spirals inward, heats up as it heads toward the black hole, and produces a steady stream of X-rays.
But under certain conditions, stable flow within the disk depends on the rate of matter flowing into it from the companion star.
At certain rates, the disk fails to maintain a steady internal flow and instead flips between two dramatically different conditions - a cooler, less ionized state where gas simply collects in the outer portion of the disk like water behind a dam, and a hotter, more ionized state that sends a tidal wave of gas surging toward the centre.
'Each outburst clears out the inner disk, and with little or no matter falling toward the black hole, the system ceases to be a bright source of X-rays,' said John Cannizzo, a Goddard astrophysicist.
'Decades later, after enough gas has accumulated in the outer disk, it switches again to its hot state and sends a deluge of gas toward the black hole, resulting in a new X-ray outburst.'
This phenomenon, called the thermal-viscous limit cycle, helps astronomers explain transient outbursts across a wide range of systems, from protoplanetary disks around young stars, to dwarf novae - where the central object is a white dwarf star - and even bright emission from supermassive black holes in the hearts of distant galaxies.
Calculating a black hole: How jets billow out from the black hole accretion disk
This disk of matter orbits the black hole at nearly the speed of light, feeding the black hole a steady diet of superheated material. Over time, this disk can cause the black hole to spin in the same direction as the orbiting material.
Caught up in this spiraling flow are magnetic fields, which accelerate hot material along powerful beams above the accretion disk.
The resulting high-speed jet, launched by the black hole and the disk, shoots out across the galaxy, extending for hundreds of thousands of light-years. These jets can influence many galactic processes, including how fast stars form.
A jet’s trajectory may help scientists understand the dynamics of black holes in the region where their gravity is the dominant force. Doeleman says such an extreme environment is perfect for confirming Einstein’s theory of general relativity - today’s definitive description of gravitation.
'Einstein’s theories have been verified in low-gravitational field cases, like on Earth or in the solar system,' Doeleman said.
Nearly every galaxy rotates around a black hole - and once mass passes the event horizon, it will not return
'But they have not been verified precisely in the only place in the universe where Einstein’s theories might break down ' which is right at the edge of a black hole.'
According to Einstein’s theory, a black hole’s mass and its spin determine how closely material can orbit before becoming unstable and falling in toward the event horizon.
Because M87’s jet is magnetically launched from this smallest orbit, astronomers can estimate the black hole’s spin through careful measurement of the jet’s size as it leaves the black hole.
Until now, no telescope has had the magnifying power required for this kind of observation.
'We are now in a position to ask the question, ‘Is Einstein right?’' Doeleman says. 'We can identify features and signatures predicted by his theories, in this very strong gravitational field.'
The team used a technique called Very Long Baseline Interferometry, or VLBI, which links data from radio dishes located thousands of miles apart. Signals from the various dishes, taken together, create a 'virtual telescope' with the resolving power of a single telescope as big as the space between the disparate dishes. The technique enables scientists to view extremely precise details in faraway galaxies.
Using the technique, Doeleman and his team measured the innermost orbit of the accretion disk to be only 5.5 times the size of the black hole event horizon.
According to the laws of physics, this size suggests that the accretion disk is spinning in the same direction as the black hole ' the first direct observation to confirm theories of how black holes power jets from the centers of galaxies.
The team plans to expand its telescope array, adding radio dishes in Chile, Europe, Mexico, Greenland and Antarctica, in order to obtain even more detailed pictures of black holes in the future.
Christopher Reynolds, a professor of astronomy at the University of Maryland, says the group’s results provide the first observational data that will help scientists understand how a black hole’s jets behave.
'The basic nature of jets is still mysterious,' Reynolds says.
'Many astrophysicists suspect that jets are powered by black hole spin ... but right now, these ideas are still entirely in the realm of theory. This measurement is the first step in putting these ideas on a firm observational basis.'

A unique spiral structure encircling a dying star has been captured by scientists for the first time.
The spectacular picture is one of the first to come from the world’s most expensive ground-based telescope which produces images ten times sharper than Hubble.
It was built to study molecular clouds like the one around the red giant R Sculptoris which is 780 light years from Earth.
In 1006, the world stopped and stared as, light-years across space, a star exploded in a supernova - briefly outshining the rest of the entire galaxy as it gave out its dying breath.
Supernova SN 1006 was seen all over Earth that Spring, shining in the sky with enough force that you could read a book outside at midnight - but scientists today have revealed that, despite its cosmic call, the star was all alone.
Many supernovas occur when two stars collide - or are at least close enough to disrupt and destabilise each other - but SN 1006's death appears to be self-initiated.
Alone in the skies: The remains of SN 1006, pictured by Nasa, recalls a time when the people of Earth would have stopped and stared at the new star in the sky
There have only been a few recorded supernova sightings in human history - each time they by turn puzzled or alarmed the people of the era.
The details recorded through history have helped modern-day astronomers investigate the sightings and provide scientific explanations for what was seen.
Early sky-watchers often provided good detailed analaysis, such as the Egyptian Arabic astronomer Ali ibn Ridwan, who noted that SN 1006 appeared low on the southern horizon.
He added: '[The] spectacle was a large circular body, 2½ to 3 times as large as Venus.
'The sky was shining because of its light. The intensity of its light was a little more than a quarter that of Moon light..'
Meanwhile Benedictine abbey monks gave their description of the sighting: '...[In] a wonderful manner this was sometimes contracted, sometimes diffused, and moreover sometimes extinguished.
'It was seen likewise for three months in the inmost limits of the south, beyond all the constellations which are seen in the sky'.
This ribbon of heated gas is caused by the shock wave of SN 1006: Since then, that shock wave has been moving through space at about six million miles an hour across a diameter of 60 light years. The orange objects in the background are distant galaxies
Now astronomers at the Paranal Observatory in Chile have scanned the skies around SN 1006 - and not found any stars - or the remains of other stars - within 16.5 light years.
Instead, it is likely the star began to collapse in on itself through gravitational forces - reaching a point where it could no longer support its own mass.
Within seconds, a large proportion of the star would have undergone nuclear fusion - and exploded, shining potentially billlions of times brighter than the sun, releasing enough explosive force to send the star's outer shell forward at around four per cent the speed of light.
And the star would have died alone - but not unobserved.
They are one of the most spectacular views a human could hope to see - and next year a comet which could outshine the moon is due to fly by the Earth.
Comet ISON is visiting the inner solar system and is set to put on spectacular views for the Northern Hemisphere across November and December as it heads towards the sun.
It may prove to be brighter than any comet of the last century - visible even in broad daylight - and this may end up being its one and only trip to the solar system, as its trajectory may see it plunge into the sun in a fiery death.

Spotted in space: Two astronomers from Russia discovered the icy ball, pictured here dimly lit against background stars
It is currently moving inwards from beyond Jupiter, and as it approaches the Earth, the 'dirty snowball' could produce a dazzling display, burning brighter than the moon and potentially being visible in broad daylight.
The comet, discovered by astronomers using the International Scientific Optical Network telescope in Russia, will pass within two million miles of the sun's surface - making it s 'sun-grazing' comet.
It is on a 'parabolic' orbit, which means it probably originated from the outer skirts of the solar system, perhaps from the Oort cloud - a mass of icy debris which lies 50,000 times further from the sun than the Earth does.
If comet ISON survives the encounter, it could take thousands - potentially millions - of years before the comet passes back through the inner solar system.
COMETS: THE REGULAR VISITORS TO OUR PLANET
Hale-Bopp sailed overhead, leaving two trails: An ionic trail of magnetically-charged particles facing directly away from the sun (left), and a trail of dust and debris (right)
Comets are dusty balls of ice, which generally originate from the Kuipler belt - a region of icy small bodies beyond Neptune.
Occasionally, a comet gets dislodged from its orbit, and plunges in to the inner solar system.
They differ from asteroids, which are made of metal or rock, and are usually the left over remnants of planets or moons.
Comets are not really reflective - they only reflect 4% of the the Sun's rays, about the same as coal. So although they look brilliantly white from Earth, they are black at the surface.
Halley's comet is the most well-known, named after Edmond Halley who noted the regular 75-76-year appearance of a comet, and predicted it would return in 1758, although sadly the astronomer died 16 years before he was proved correct.
Halley's comet has passed within a fraction of the Earth before - in 1910 the Earth even moved through the comet's tail.
Sadly, the 1986 re-appearance was the worst for 2,000 years, as the Earth and the comet were on opposite sides of the sun.
The comet will begin brightening once it gets within Jupiter's orbit, as the sun's heat begins boiling the ice locked within the comet, converting it directly into gas. It is likely to recall the excitement of Comet Hale-Bopp, which sailed past the Earth in 1997, appearing as a static-looking smear in the skies across the Northern Hemisphere. It is also set to outshine 'the greatest comet of the last century' - Comet McNaught, which shone brighter than Venus as it passed above the southern hemisphere in 1965.
Comets are known as 'dirty snowballs', although technically a better definition would be 'snowy dirtballs', as comets are generally rocky at the surface, with chemical-laden ice within the interior.
As the ice and chemicals heat up, they erupt as brilliant jets which can form tails lasting hundreds of thousands of kilometres in length.
The comet is expected to be bright throughout late November and early December.
Robin Scagell, vice-president of the Society for Popular Astronomy, said: 'This is a very exciting discovery. 'The comet looks like it could become a very spectacular sight in the evening sky after sunset from the UK in late November and early December next year.
'Our members will be eagerly following it as it makes its first trip around the Sun and hoping to see it shining brilliantly and displaying a magnificent tail as it releases powerful jets of gas and dust.
