Within the first week of the OSIRIS-REx probe arriving at Bennu, it has already detected water on the asteroid. On December 3, 2018, the probe reached the diamond-shaped asteroid in NASA’s first asteroid-sample return mission.
The scientific team pointed three instruments onboard the spacecraft in the direction of Bennu and started their observations. They received data from the probe’s two spectrometers – OVIRS (OSIRIS-REx Visible and Infrared Spectrometer) and OTES (OSIRIS-REx Thermal Emission Spectrometer) – that showed the existence of molecules that contain oxygen and hydrogen atoms that are bonded together. These molecules, which are called “hydroxyls”, are believed to exist across the entire asteroid in water-bearing clay minerals that would indicate that the rocky material on Bennu connected with water at one point. Since Bennu is too small to have ever had liquid water, it’s very possible that it was present on its parent body which was a much bigger asteroid.
Amy Simon, who is the OVIRS deputy instrument scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said, “The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study the composition of primitive volatiles and organics.” She went on to say, “When samples of this material are returned by the mission to Earth in 2023, scientists will receive a treasure trove of new information about the history and evolution of our solar system.”
The surface of Bennu contains a mix of rocky, boulder-filled regions, as well as a few smooth regions that do not have boulders. While there are more boulders than initially thought, there is one in particular that scientists are interested in and it’s located at the asteroid’s South Pole. Initial calculations from the OCAMS (OSIRIS-REx Camera Suite) show that the huge boulder is around 164 feet high by 180 feet wide.
This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km).
Credits: NASA/Goddard/University of Arizona
The mission is only conducting preliminary surveys of Bennu at this point as it performs flybys over the asteroid’s North Pole, South Pole, and equator at a distance as close as 4.4 miles. Once they determine Bennu’s mass, scientists can then create a plan for the spacecraft to enter its orbit. While performing the surveys, it also gives the Canadian Space Agency’s OLA (OSIRIS-REx Laser Altimeter) its first chance to make observations.
The OSIRIS-REx probe will enter Bennu’s orbit on December 31st and will stay in orbit until the middle of February in 2019. At that point, it will leave the asteroid’s orbit and conduct more flybys for the following survey phase. The probe will get within one mile of the asteroid’s surface which will set a record for the closest orbit of a planetary body by a spacecraft, as well as another record for the smallest body ever orbited by a spacecraft. The OSIRIS-REx is set to leave the asteroid in March 2021 and head back to Earth.
Triangular Craft filmed during docking procedure SpaceX Dragon Capsule and the ISS?
Triangular Craft filmed during docking procedure SpaceX Dragon Capsule and the ISS?
During the live coverage on Saturday, December 8 International Space Station crew members used the station’s 57.7-foot (17.6-meter) robotic arm to capture SpaceX's Dragon spacecraft and attach it to the orbiting laboratory.
But during the docking procedure of the dragon capsule and the International Space Station suddenly a triangular object comes into the view moving behind the Dragon capsule until it disappears into space.
It is unknown whether the object originated from the ISS or if it was a UFO.
Below the footage of the the triangular object that looks like a typical TR-3B at the moment it passes the Dragon capsule during the streaming of the docking procedure.

Gold UFO Seen Observing Astronaut On Spacewalk At Space Station, Dec 2018, UFO Sighting News.
Gold UFO Seen Observing Astronaut On Spacewalk At Space Station, Dec 2018, UFO Sighting News.
Date of sighting: December 2018
Location of sighting: International Space Station
This is a golden UFO that came very close to the space station yesterday. An astronaut was outside during a spacewalk rearing the outer walls insulation when an alien craft flew past observing him on live Internet camera.
The UFO is only visible due to its golden color and the bright light reflecting off the space station onto the UFO. The space station flashes at one point and the entire UFO is visible for a split second.
This is 100% proof that alien craft are closely observing the space station and highly interested in how humans deal with the stress of spacewalks.

UFO in broad daylight over New York makes comet tail to fool public, Dec 2018, UFO Sighting News.
Date of sighting:December 2018
Location of sighting: New York, USA
This UFO was seen over New York this week and its got people thinking it could be a comet or asteroid that got too close. NASA did say an asteroid shower was expected, but this thing looks huge. The disk like object made a comet like tail behind it to deliberately confuse and fool people into thinking its a comet. However its too far inside our atmosphere and it would be pulled in by gravity.
Sure NASA also said that comet 46P was going to be close this week, however this is within only a few miles from the surface of earth. Look at the detail on the thick disk of the spacecraft in fronton the tail. Its not a comet, NASA just saw an incoming UFO that was huge and asked them to make a tail when entering our atmosphere before they go to their base somewhere below the ocean.

ORLANDO, Fla. — The discovery of intelligent aliens would be mind-blowing in many respects, but it could present a special dilemma for the world's religions, theologians pondering interstellar travel concepts said Saturday (Oct. 1).
Christians, in particular, might take the news hardest, because the Christian belief system does not easily allow for other intelligent beings in the universe, Christian thinkers said at the 100 Year Starship Symposium, a meeting sponsored by the Defense Advanced Research Projects Agency (DARPA) to discuss issues surrounding traveling to other stars.
In other words, "Did Jesus die for Klingons too?" as philosophy professor Christian Weidemannof Germany's Ruhr-University Bochum titled his talk at a panel on the philosophical and religious considerations of visiting other worlds.
"According to Christianity, an historic event some 2,000 years ago was supposed to save the whole of creation," Weidemann said. "You can grasp the conflict." [10 Alien Encounters Debunked]
Here's how the debate goes: If the whole of creation includes 125 billion galaxies with hundreds of billions of stars in each, as astronomers think, then what if some of these stars have planets with advanced civilizations, too? Why would Jesus Christ have come to Earth, of all the inhabited planets in the universe, to save Earthlings and abandon the rest of God's creatures?
Aliens and religion can still coexist
Weidemann, a self-described protestant Christian, suggested some possible solutions. Perhaps extraterrestrials aren't sinners, like humans, and therefore aren't in need of saving. However, the principle of mediocrity — the idea that your own example is most likely typical unless you have evidence to the contrary — casts doubt on this, he pointed out. [10 Wildest Ways to Contact Aliens]
"If there are extraterrestrial intelligent beings at all, it is safe to assume that most of them are sinners too," Weidemann said. "If so, did Jesus save them too? My position is no. If so, our position among intelligent beings in the universe would be very exceptional."
Another possibility is that God incarnated multiple times, sending a version of himself down to save each inhabited planet separately.
However, based on the best guesses of how many civilizations we might expect to exist in the universe, and how long planets and civilizations are expected to survive, God's incarnations would have had to be in about 250 places simultaneously at any given time, assuming each incarnation took about 30 years, Weidemann calculated.
Religious food for thought
If God truly became corporeal and took human form when Jesus Christ was born, this wouldn't have been possible, Weidemann said. [How Astronomy and Religion Intersect]
Rev. Thomas Hoffmann, a protestant pastor in Tulsa, Okla., said that the issues Weidemann raised were "really on target."
"If life is discovered elsewhere, unfortunately we need to have more discussion about it," Hoffmann said. "I think this is a very robust conversation we need to have."
While the discovery of extraterrestrial intelligence would likely spur profound soul-searching for people of all faiths, many of the world's religions might have an easier time accommodating the knowledge than Christianity, said theologist Michael Waltemathe, also of the Ruhr-University Bochum.
"It seems to be only a problem of Christianity," Waltemathe said.
In Islam, for example, Muhammad was a prophet, or messenger of God, not God incarnate, so additional prophets could have simultaneously visited other planets to save extraterrestrial species, he said. And Hindus already believe in multiple deities, so accommodating more to guard over alien civilizations may not be difficult.
Ultimately, though, the discovery of intelligent aliens isn't likely to pose a serious crisis for Christianity, either, Hoffmann said. After all, the religion has survived challenging scientific revelations before.
"Religion is essentially conservative," Hoffmann told SPACE.com. "You can put almost anything in its face and it's going to shake out a little bit, and then it's going to drop right back down. We've seen this happen historically."

Fox News published astartling articleMonday (Dec. 3) with the headline "NASA scientist says Earth may have been visited by aliens." Unsurprisingly, that news rocketed around the web, with similar articles soon turning up in the New York Post, Russia Today and The Daily Wire. (Fox appears to have been the first major U.S. news source to run with the story.)
These articles are based on a document on NASA's website by Silvano Colombano, a researcher at NASA's Ames Research Center in Mountain View, California. It really does argue that scientists should at least take seriously the notion that aliens may have visited planet Earth. But Colombano told Live Science that the coverage on Fox News and elsewhere misrepresented what he was trying to say when he wrote it.
"It is not accurately represented," he said. "My perspective was simply that reports of unidentified aerial phenomena should be the object of serious study, even if the chance of identification of some alien technology is very small." [13 Ways to Hunt Intelligent Aliens]
There's some nuance here. Colombano really does believe, as Fox News wrote, that aliens "may" have visited planet Earth. As in, it's theoretically possible that this has happened, not entirely impossible, and worth looking for evidence that it has. But that's not the same as expecting to actually find any such evidence, or believing that there's a good chance aliens are scuttling around under our noses — an impression you might get if you read Fox News's article.
Though Colombano's name and email address appear right on top of the document, he said Fox News did not contact him before publishing their story. (Live Science has reached out to Fox News to confirm this, but has not yet heard back.) Fox described the document as a "new research paper" — a term usually used to describe formal articles intended for publication in research journals and making conclusions based on evidence and the scientific method.
But that's not what this document is.
"The context was a presentation delivered last spring at a meeting of the SETI (Search for Extraterrestrial Intelligence) Institute," he said.
"The meeting was to get feedback from scientists as to future directions for the Institute's research program," Colombano said.
The document accompanied a talk he gave in which he suggested that perhaps the notion of aliens visiting Earth isn't quite as ridiculous as most scientists believe, and that SETI might devote some resources to systematically hunting through UFO reports and other data for evidence that this has happened — to hunt for a faint, unlikely signal in a lot of messy noise.
In other words, it was a speculative piece of writing intended to persuade other scientists to spend their resources on a long-shot project — not an argument about whether or not aliens have actually visited Earth. Colombano's position is that it's possible, but not necessarily likely.

Purple UFO Videotaped over Waterford, Ireland
Purple UFO Videotaped over Waterford, Ireland
unusually colored and shaped object...
Waterford, Ireland - 12-09-18
A recent video has been uploaded to MUFON by submitter 96894. The man's wife Anita filmed two videos during the evening of December 9, 2018.
The object in question was seen over Waterford, Ireland and shows a very unusually colored and shaped object.
What we see is a purple-colored donut shape with several breaks in the circular shape. The object is adorned on top with no less than 18 brightly lit white lights.
The object fades in and out of focus from time to time, but is clearly seen most of the time. The question at hand is what this strange object is.
The UFO could be anything from an unusual drone to an inflated object of some kind, or something more sinister. Take a good look and see if you can identify it.

BEAUTIFUL NEW IMAGES SHOW CLOUDS OF DUST FORMING INTO PLANETS
BEAUTIFUL NEW IMAGES SHOW CLOUDS OF DUST FORMING INTO PLANETS
ALMA (ESO/NAOJ/NRAO)
KRISTIN HOUSER
Rings Of Fire
If you’re in the market for a new desktop wallpaper, we have 20 suggestions.
A protoplanetary disk is the ring of dust and gas that surrounds a young star. As time passes, the material in the disk begins to coalesce into larger and larger objects, forming everything from asteroids to entire planets.
Now, thanks to a powerful system of radio antennas in the Chilean desert, we have 20 stunning, high-resolution images of such systems — and they are more than desktop-worthy.
According to the program’s website, its goal is to study the smaller objects in protoplanetary disks to determine how those objects related to planet formation.
These images are helping it achieve that goal. According to a news release, the team was able to theorize based on this ALMA data that large planets can form much more quickly than previously thought. They also determined that the planets typically form far from their host stars.
ALMA Matters
In addition to these gorgeous — and data-rich — images produced by DSHARP, just last week an international team of researchers published the preliminary results of a survey in which it used ALMA to image 32 stars surrounded by protoplanetary disks.
Clearly, ALMA has proven to be one of our most useful tools for studying protoplanetary disks, and it’s only been operational for five years. Who knows what sorts of beautiful and useful data the array might produce in the future?
A Near Earth Object (NEO) is a comet or asteroid that’s path is pulled by gravity causing it to pass close to the Earth. There are around 19,000 NEOs that NASA and other scientific communities keep track of. Theses astronomers try to track all of these objects so that they can warn us if there is an impending collision with the Earth. Unfortunately, there is no way that they can keep track of all of these objects. Many of them aren’t noticed until after they pass the Earth; if they get noticed at all.
The thought of a NEO is already scary enough on its own but now there is a developing theory that some of these objects may contain intelligent, alien life. It is really hard for us to comprehend how this is possible but you have to remember that these alien species are thousands of years (if not more) advanced than us humans.
How Could Aliens Use a NEO as a Space Ship?
When we think about a space ship or UFO we usually think about a metal vehicle with a propulsion system of some kind. A NEO traveling at fifty-thousand miles an hour through the galaxy is the perfect vessel to use for long space flights. Some of these asteroids are big enough to support colonies of aliens. If advanced aliens colonized one of these asteroids then they could easily harness its energy.
Asteroids Are Constantly Passing Earth
NEO’s Are Not Always Predictable
One of the reasons that we think that there might be alien manipulation involved on some of these NEOs is because some of their paths seem to change in ways that are not expected to Astronomers. Astronomy is a very complicated science, that I don’t claim to understand at all, so I will just have to assume that the scientists know what they are talking about.
There are many things that us humans still don’t understand about the Universe, but one of the theories to why these objects change courses unexpectedly is because they are being manipulated, intentionally, by an intelligent alien.
Turning An Asteroid Into a Space Ship or UFO
The process of turning an asteroid into a space ship is more plausiblethan you might think. Catching up to the asteroid would be the hardest part. Once a colony of aliens or alien androids are on the object, they could manipulate its trajectory pretty easily. Turning the object would only take a little nudge of a propulsion device. The aliens could also speed up the asteroid by using the gravity of larger objects. By using these techniques, an alien, asteroid space ship could travel indefinitely through the universe while using almost no power.
Time is Relative
If you are like me then you are probably already poking holes in this theory. It is just a theory after all. So is Theoretical Physics but people act like string theory is a fact. Anyways. One of the problems with this theory is that even though these asteroids are traveling at really high speeds, it would still take them forever to get anywhere. When objects are thousands of light years away, thousands of miles an hour isn’t fast enough to get anywhere.
While time and distance do cause problems with this theory, it doesn’t completely destroy it. This mode of transportation would be useful for long-term missions. You always have to remember that this space ship isn’t full of humans. Aliens life spans could be tens of thousands of years. Or more! A really advanced species of aliens could have learned how to fight off death permanently. Eternal life is already in the works here on Earth, so I am sure that advanced aliens have already thought about it. If aliens could live this long then to them a few thousand years trip would be possible.
Good Ole Suspended Animation
We can’t forget about the old Sci Fi classic idea of suspended animation either. While it is just a movie trick here on Earth, aliens could really be using this method to travel for long periods of space and time. Other ways to get around the slow travel speed of using a NEO as a space ship are wormholes, warp engines and androids. If a typical alien UFO can do it then one of these converted asteroids can too. We can’t comprehend what these advanced alien species are capable of. This is why they were so often confused with Gods in the past.
UFOs Asteroid Air Craft Carrier
I hope that, by reading this, you now realize how possible it is that aliens could be using NEOs as space ships. It doesn’t have to be an object near Earth, of course, but that is probably the only way that we will ever find out about it. At least in our life times. Aliens could be using these asteroids like we use air craft carriers. Maybe one day, a fleet of UFOs will pop out of a passing comet or asteroid. Hopefully they will be friendly. Until then, we will keep speculating and watching the skies.
No, it’s not a Shadow of the Colossus movie. It’s Captive State.
Photo: Focus Features
We hate to be presumptuous, but this new trailer blew us away, so there’s a chance it might do the same for you.
So far, trailers for Captive Statehavebeen good. No better, no worse, just good. The framing of the film, set in a world years after aliens have invaded and won, is excellent, but so far its trailers have focused on the film’s more personal aspects. This new trailer, though? Holy shit. It opens things up in a major, major way. Check it out.
Look at all those aliens! Those spaceships! That political intrigue! The father-and-son dynamics! All of those things and more (like that awesome cast: John Goodman! Vera Farmiga!) make this movie look pretty special. Then again, that’s the job of a trailer—to make anything look good—so there’s always an outside chance the movie won’t live up to all this promise.
But, we don’t think so. That footage and cast are too good, and director Rupert Wyatt is too talented to waste such an incredible premise. If the movie ended up being bad, it would be an awful disappointment.
FIRST LOOK One of the first images NASA’s Parker Solar Probe took during its close encounter with the sun shows a streamer of plasma in the outer solar atmosphere, or corona. The probe took this image November 8 at a distance of about 27 million kilometers from the sun’s surface. The bright dot below the streamer is Jupiter.
PARKER SOLAR PROBE/NASA AND NAVAL RESEARCH LABORATORY
NASA’s Parker Solar Probe has met the sun and lived to tell the tale.
The sun-grazing spacecraft has already broken the records for the fastest space probe and the nearest brush any spacecraft has made with the sun. Now the probe is sending data back from its close solar encounter, scientists reported December 12 at the American Geophysical Union meeting in Washington, D.C.
“What we are looking at now is completely brand new,” solar physicist Nour Raouafi of Johns Hopkins University Applied Physics Lab in Laurel, Md., said at a news conference. “Nobody looked at this before.”
Parker launched August 12 (SN Online: 8/12/18) and will make 24 close passes by the sun over the next seven years, eventually going to within about 6 million kilometers of the sun’s surface (SN: 7/21/18, p. 12). The spacecraft made its first close flyby November 6, swooping to within roughly 24 million kilometers of the solar surface. That’s about twice as close to the sun as the previous closest spacecraft, the Helios spacecraft in the 1970s. At peak speed, Parker was racing at about 375,000 kilometers per hour, roughly twice Helios’ speed.
But because the probe was on the opposite side of the sun from Earth during the flyby, Parker didn’t start relaying its observations until December 7.
After the probe emerged from behind the sun, the Parker team got its first up-close look at the wispy outer solar atmosphere, called the corona. One of the first images from Parker’s camera shows unprecedented detail in a solar streamer, a filament of plasma in the corona. The team hopes that Parker’s data will help solve the mystery of why the corona is about 300 times as hot as the sun’s surface (SN Online: 8/20/17).
Only about one-fifth of the data recorded during Parker’s initial flyby will reach scientists before the sun gets between Earth and the spacecraft again. The rest of the data will be downlinked next year, between March and May. Scientists hope to start publishing results soon after.
“If you ask any scientist in the team or even outside what to expect, I think the answer would be, we don’t really know,” Raouafi said. “We are almost certain we’ll make new discoveries.”
Risk of impact! Dangerous asteroid "BENNU" racing towards the earth
The asteroid "Bennu" is still racing towards our planet (TAG24 reported). It weighs 79 million tons and has a diameter of 500 meters. What can save us now?
Or better, who can save us now? Answer: NASA! They already have a "plan" to avert the impact and annihilation of mankind.
NASA has sent the "Osiris Rex" probe into space for this purpose. And now - after two years and over 650 million kilometres covered - it has finally reached "Bennu"!
"We have arrived", was the message from the US space agency Nasa on Monday. The arrival position of the probe, which was launched in September 2016 from the Cape Canaveral spaceport, is about 20 kilometres from "Bennu".
"Osiris Rex" will now spend about a year investigating Bennu and finding a suitable site for taking a sample.
"Osiris Rex" (short for: Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) is the first US missile to set off for an asteroid and send a sample back.
If everything goes according to plan, the probe, which is about six meters long and weighs 2100 kilograms, will approach Bennu in 2020 so far that it can absorb a sample of 60 to 2000 grams.
In 2023, a capsule with the sample is to return to Earth. The NASA scientists hope that the mission, which will cost around one billion dollars, will provide them with insights into the origin of our solar system. According to the scientists, the asteroid is to be destroyed.
For this even nuclear missiles could be used. But then there is also the danger that irradiated asteroid pieces will calculate the earth.
The deep black Bennu with a diameter of 500 meters should soon come very close to the earth. As date for a possible impact the 25th September 2135 was computed.
Thus already in 117 years. And the impact risk exists! Soothing: It is very low, according to NASA. Nevertheless, "Bennu" is one of the most dangerous asteroids currently known.
Triangular Shaped Object Spotted On Night Vision Over Melbourne, Dec. 8, 2018
Triangular Shaped Object Spotted On Night Vision Over Melbourne, Dec. 8, 2018
On December 8, YouTube's "UFO Lou" caught a triangular shaped object, moving quickly with his P8079HP Night Vision Device. Kind of makes me want to build a night scope, to mount somehow on my Nikon Coolpix P900. Definitely, some weird stuff flying overhead in our darkened skies.
A huge lake of liquid water has been found on Mars. The groundbreaking discovery comes after years of evidence of the Red Planet's watery pastandicy present, but this is the first time a significant amount of the life-giving liquid has been detected. Discovered through satellite radar readings, the lake lies beneath the ice caps at the south pole of Mars, and has profound implications for future missions and the search for extraterrestrial life.
According to its discoverers, the lake lies below 1.5 km (0.9 mi) of solid ice, and stretches 20 km (12.4 mi) wide. Although temperatures at that spot plummet to about -68° C (-90° F), the water remains in a liquid form thanks to the heavy presence of sodium, magnesium and calcium salts. This, along with the immense pressure of the ice from above, lowers the freezing point.
The discovery was made by astronomers using the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) onboard the Mars Express orbiter. This instrument beams radar pulses down to the planet's surface and measures how the waves reflect back to the spacecraft, which can tell scientists what kind of materials lie down there, even below the surface.
Using MARSIS to survey a region around the south pole of the Red Planet, the team collected 29 sets of radar samplings between May 2012 and December 2015. A section of this area returned very sharp changes in the radar signals, showing up as a bright spot in the image that's consistent with a water interface. The radar profile, the researchers say, closely matches those of subglacial lakes here on Earth, beneath the ice sheets of Greenland and Antarctica.
Although it seems like "water found on Mars" headlines have been doing the rounds for years, this discovery is really what it's all been building to. The majority of modern Mars is dry and barren, but plenty of evidence has been found that the Red Planet used to be a much wetter place. NASA studies suggest a vast ocean covered the planet's northern hemisphere some 4.3 billion years ago, and lakes may have filled and emptied repeatedly over tens of millions of years in places like Gale Crater, the landing site of the Curiosity rover.
The discovery of a large, stable reserve of liquid water on Mars is massive, giving us new potential targets for future missions and places to search for signs of past or present microbial life – although the sheer saltiness of it might kill those hopes.
The research was published in the journal Science.
Earth is teeming with life, but a new project shows most of it isn't where you'd expect. A decade-long study has now taken a census of one of the largest and least-understood ecosystems on the planet – the "deep biosphere" that extends several kilometers into the planet's crust. Among the finds are bizarre creatures that can survive at record depths, pressures and temperatures, and even "zombie" bacteria that may live (in a loose sense of the word) for millions of years at a time.
The project, known as the Deep Carbon Observatory, is the result of an international collaboration of scientists over almost 10 years. Data was collected from hundreds of sites across the world, with samples taken on land from mines and boreholes 5 km (3.1 mi) deep and up to 2.5 km (1.6 mi) under the seafloor.
Using that data, the researchers modeled these deep-Earth ecosystems, and estimated the amount of life down there. According to their calculations, up to 6 x10^29 cells (that's a 6 followed by 29 zeroes) live deep beneath the continental landmasses. When you include the life beneath the seafloors, there's approximately 15 to 23 billion tonnes of carbon biomass. The deep biosphere itself likely occupies up to 2.3 billion cubic km, which is almost twice the total volume of the planet's oceans.
"A decade ago, we had no idea that the rocks beneath our feet could be so vastly inhabited," says Isabelle Daniel, of the University of Lyon 1 in France. "Experimental investigations told us that microbes could potentially survive to great depth; at that time, we had no evidence, and this has become real 10 years later. This is simply fascinating and will surely foster enthusiasm to look for the biotic-abiotic fringe on Earth and elsewhere."
So, what kind of creatures live down there? The team says that all three domains of life – the broadest groups on the tree of life – are represented, with a genetic diversity at least as extensive as there is here on the surface. Two of those domains, bacteria and archaea, dominate the deep biosphere, which might contain as much as 70 percent of Earth's total amount of those groups. The vast majority of them are still completely unknown to science.
The creatures found in this deep biosphere consistently break records for the known extremes that life can survive under. The deepest-dwelling lifeforms have been discovered down to 5 km (3.1 mi) below land and 10.5 km (6.5 mi) below the ocean's surface.
But perhaps the strangest of all are bacteria that the researchers describe as "zombies." These organisms have life cycles on almost geologic timescales, millions or even tens of millions of years. But it's not much of a life – they don't really grow or undergo cellular division, instead focusing the little energy on hand into just barely maintaining their existence.
The scientists say we've barely begun to scratch the (sub)surface of the deep biosphere. Not only do most species remain unknown, but it's a mystery how they live, reproduce, move around, affect surface life and are affected by natural events like earthquakes and unnatural ones like fracking.
Researchers on the Deep Carbon Observatory project are presenting their findings at the American Geophysical Union meeting this week, which was described in recent papers published in Geobiology and Nature Geoscience, among others.

WASHINGTON— NASA's Mars InSight landerhas settled into its new home on Elysium Planitia and is preparing to deploy its instruments — and if all goes well, one device's work should be complete by March.
That instrument is InSight's self-hammering heat probe, nicknamed the "mole," which is designed to measure heat production and flowwithin the interior of Mars. To do that, the instrument has to drill down about 16 feet (5 meters) into the Martian regolith — and that procedure is currently scheduled to begin in January, the mole's principal investigator said yesterday (Dec. 11) during a presentation at the annual meeting of the American Geophysical Union.
Of course, this is space exploration, and that means there's still a chance that something could go wrong. "They're speaking about the seven minutes of terror on landing, now I'm saying we have two months of terror in front of us when we penetrate into the surface," said Tilman Spohn, a planetary scientist at the German space agency, which is known by its German acronym, DLR.

The heat probe needs to wait its turn, with the lander's supersensitive seismometer and its protective shielding being deployed first. That process will take about a month and is scheduled to begin next week, Spohn said.
If that goes well, the heat probe will be the next to move, with deployment beginning in mid-January. The drilling process will take about two months, since the probe regularly stops to produce a burst of heat and measure how that heat moves through the rock at its current depth.
What worries Spohn is that a large rock — 3 feet (1 m) in diameter or so — would stymie the probe's drilling mechanism, which relies on pushing aside dirt. Smaller rocks it can either push aside or burrow around, and has demonstrated that ability during tests in rock chambers here on Earth.
If a blockage does occur, how far the probe has managed to travel will determine how helpful the results are to scientists. "The less we penetrate, the worse it will be," Spohn said. If it's just 3 feet (1 m) or so deep, the team will need to rely on more intensive modeling. But if it reaches 10 feet (3 m), which should occur around mid February, the team will be pleased — and if it can reach the full depth of 16 feet (5 m) around March 10 or so, all the better.
Spohn is pleased with InSight's landing site, which is just as flat and rock-free as scientists were hoping for. "We had a lot of luck, we have to say," he said, noting that the robot touched down near — but not inside — a crater. "Had we landed there we would have been in some trouble."
Its main job is to spot the stars, but an ultrasensitive navigation camera onNASA's Juno spacecraftis returning amazing images of Jupiter's rings, auroras, lightning, and even its moonlit dark side.
Scientists discussed the results from the camera alongside other Jupiter revelations during a briefing Dec. 12 at the American Geophysical Union's annual meeting in Washington, D.C. Juno is approaching the halfway point on its primary mission, with its 16th science pass by the planet set for Dec. 21.
That camera is called the Stellar Reference Unit, or SRU for short. According to Heidi Becker, Juno's radiation monitoring investigation lead at NASA's Jet Propulsion Laboratory in California, the camera's "day job" is to cut through interference from the intense radiation surrounding Jupiter to spot the stars, comparing them to a database to figure out Juno's precise location and orientation during its 53-day, elongated orbits of the gas giant.

"It's really hard to do that engineering job on Juno because we're flying Juno through the most violent planetary radiation environment there is," Becker said during the briefing, which was webcast live online. "Even though we had to shield the SRU more than six times heavier than we've shielded the radiation vault [which protects Juno's main computer and other sensitive components], there still are very high-energy electrons in that environment that will penetrate the SRU shielding and create this static that you see in the star image."
But rather than seeing a disruption, the team at JPL uses that "snow" to make measurements of how intense the radiation is over different parts of Jupiter — they've already noticed that the high-latitude radiation belt is less powerful than models suggested.
"We use noise as data to figure out what the environment is on the outside of Juno, because we're flying where nobody flew before," Becker said.
This is the first view ever taken from inside Jupiter's rings, snagged by Juno's Stellar Reference Unit camera during its first science encounter with the planet on Aug. 27, 2016. The three stars of Orion's Belt can be seen in the lower right, and Betelgeuse shines just above the rings.

During its first data-collecting dive past Jupiter in August 2016, SRU grabbed the first-ever view of Jupiter's faint rings from the inside. The image also reflects the navigation side of SRU — Orion's Belt can be seen dotting down the lower right of the image, and the blazing star Betelgeuse can be seen just above the ring.
And that view was only the beginning: "Once we started to get a sense of what else the SRU can do as a low-light camera, my team and I kind of got addicted and kept asking the question: What else can this camera bring back that's new, that's never been seen before, or that's never been seen in the way that only the SRU can see it?" Becker said.

The spacecraft's main visible-light camera, called JunoCam, has been returning spectacular images for the public to process, and has proved useful for science in its own right, researchers said at the briefing. And in the low-light conditions on Jupiter's dark side, Becker said, SRU has returned views that rival that camera's detailed view of the planet's swirls.
This detailed image of Jupiter's dark side, taken during the Juno spacecraft's 11th approach of the gas giant, comes from Juno's Stellar Reference Unit camera. It was taken from just 66,000 miles above the planet's cloud tops.

"When we first saw this image, we thought 'did our data get mixed up with JunoCam's?'" Becker said. But, no, it was indeed from the SRU, with the planet's cloud tops lit by sunlight reflected off the volcanic moon Io, taken just 66,000 miles from the cloud tops.
In addition, the researchers spotted two bright dots of lightning — visible to the right of the image — providing the closest view of Jupiter's lightning from any imager. Because the spacecraft's microwave radiometer, which has also proved a good lightning detector, faces the same way as the SRU, researchers can eventually combine their measurements to learn about the phenomenon in more depth.

Juno's other instruments have provided incredible views of the planet's auroras in ultraviolet and infrared light, but because of its dark-side views SRU has been able to contribute in the visible spectrum, too, showing the ghostly lights circling the planet's pole.
The Stellar Reference Unit camera, which helps Juno navigate during its mission at Jupiter, snapped this close-up view of the northern aurora on the planet's dark side — the closest visible-light view of the phenomenon ever taken.

"This is another first: This is the closest view of Jupiter's aurora that has ever been made by a visible[-light] camera," Becker said. "It's an amazing complement to what Juno is already bringing back in the ultraviolet and in the infrared. And, again, we're seeing amazing structure because of the high resolution of the camera and Juno's close flight to the camera."
This image also reveals another dot of lighting, in the lower right, and the squiggles of high-energy electrons beaming off the planet's poles — "so SRU was doing three kinds of science when it took this picture."
"It's really exciting to see what we can see out of an engineering camera, and we're really erasing all the boundaries between who or what can make a contribution to engineering or science or art," Becker added.
The $1.1 billion Juno mission launched toward Jupiter in August 2011 and arrived in orbit around the planet in July 2016. Since then, it's examined the planet during its long, looping orbits to learn about its interior, cloud patterns and weather, magnetic field, radiation and more.
"We have already rewritten the textbooks on how Jupiter's atmosphere works, and on the complexity and asymmetry of its magnetic field," Scott Bolton, principal investigator for Juno and a researcher at Southwest Research Institute in Texas, said in a statement. "The second half should provide the detail that we can use to refine our understanding of the depth of Jupiter's zonal winds, the generation of its magnetic field, and the structure and evolution of its interior."
