Since its arrival at Bennu, the probe has been investigating the asteroid and searching for an ideal site for sample collection. Bennu is only slightly wider than the height of the Empire State Building and is the smallest body ever orbited by spacecraft. Studying Bennu with OSIRIS-REx will allow researchers to learn more about the origins of our solar system, the sources of water and organic molecules on Earth, and the hazards and resources in near-Earth space. The teleconference participants are:Lori Glaze, acting director, NASA’s Planetary Science Division, WashingtonDante Lauretta, OSIRIS-REx principal investigator, University of Arizona, TucsonCoralie Adam, OSIRIS-REx flight navigator, KinetX, Inc. Space Navigation and Flight Dynamics, Simi Valley, Calif.Rich Burns, OSIRIS-REx project manager, NASA’s Goddard Space Flight Center, Greenbelt, Md.For more information about the mission, go to nasa.gov/osirisrex or asteroidmission.org.Learn more about the big surprises at Bennu that were announced during this teleconference, and see images of the asteroid's particle plumes and its unexpectedly rugged surface. || ",

            "description": "As this visualization draws near to the northwest coast of Greenland where the Hiawatha Glacier is located, the ice sheet is cut away to show the topography of Greenland's bedrock lying beneath the ice sheet at 20x vertical exaggeration. The Hiawatha crater is clearly visible in the topography. Farther inland another, subtler circular depression can be seen. The edge picks of this depression are shown as vertical bars, while potential central peaks are marked by orange pyramids. As we rotate around the depression, the location of the best-fit circle to the edge picks appears and that circle's center is marked with an \"X\". This circle matches well with both the edge of the bedrock depression and also the residual slope of the ice surface as it flows over this depression (not shown), strongly supporting the inference that this depression is another large impact crater.This video is also available on our YouTube channel. || C2_Crater_4k.1524_print.jpg (1024x576) [111.8 KB] || C2_Crater_4k.1524_searchweb.png (320x180) [88.0 KB] || C2_Crater_4k.1524_thm.png (80x40) [7.2 KB] || C2_Crater_4k_1080p30_low.mp4 (1920x1080) [23.1 MB] || C2_Crater_4k_1080p30.mp4 (1920x1080) [47.8 MB] || C2_Crater_4k_1080p30.webmhd.webm (1080x606) [11.6 MB] || C2_Crater_4k_2160p30_low.mp4 (3840x2160) [48.2 MB] || C2_Crater_4k_2160p30.mp4 (3840x2160) [85.9 MB] || 3840x2160_16x9_30p (3840x2160) [0 Item(s)] || captions_silent.24907.en_US.srt [43 bytes] || captions_silent.24907.en_US.vtt [56 bytes] || C2_Crater_4K_YouTube.mp4 (3840x2160) [245.6 MB] || C2_Crater_4K_ProRes.mov (3840x2160) [3.4 GB] || C2_Crater_4k_1080p30_low.mp4.hwshow [190 bytes] || ",

The number practically doubles the list of planets known to humanity. Kepler spotted 3,600 potential planets within the first two years of operation by detecting slight dips in the brightness of more than 100,000 nearby stars. The challenge, however, is distinguishing the real planets from the fakes, a laborious process that involves sifting through the candidate planets, one by one. But by employing a new method that can verify multiple planets at once, researchers were able to speed up their search. About 95 percent of the newly discovered worlds are smaller than Neptune, with four orbiting within the habitable zones of their host stars. The findings suggest that small, Earth-like planets may be more abundant in our galaxy than previously thought. Watch the video to learn more. || ",

IRIS will tease out the rules governing the lowest layers of the solar atmosphere — historically some of the hardest to untangle. Known as the solar interface region, this is one of the most complex areas in the sun's atmosphere: all the energy that drives solar activity travels through it. The interface region lies between the sun’s 6,000-degree, white-hot, visible surface, the photosphere, and the much hotter multi-million-degree upper corona. Interactions between the violently moving plasma and the sun’s magnetic field in this area may well be the source of the energy that heats the corona to its million-degree temperatures, some hundreds and occasionally thousands of times hotter than the sun's surface. The chromosphere is also considered a candidate as the origin for giant explosions on the sun such as solar flares and coronal mass ejections. IRIS will use high-resolution images, data and advanced computer models to unravel how solar gases move, gather energy and heat up through the lower solar atmosphere. Outfitted with state-of-the-art tools, IRIS will be able to tease apart what's happening in the solar interface region better than ever before. || ",

            "title": "A Trio of Swift Bursts Form A New Class of GRBs",
            "description": "Three unusually long-lasting stellar explosions discovered by NASA's Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs). Two international teams of astronomers studying these events conclude that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the sun. GRBs are the most luminous and mysterious explosions in the universe. The blasts emit surges of gamma rays — the most powerful form of light — as well as X-rays, and they produce afterglows that can be observed at optical and radio energies. Swift, Fermi and other spacecraft detect an average of about one GRB each day.Traditionally, astronomers have recognized two GRB types, short and long, based on the duration of the gamma-ray signal. Short bursts last two seconds or less and are thought to represent a merger of compact objects in a binary system, with the most likely suspects being neutron stars and black holes. Long GRBs may last anywhere from several seconds to several minutes, with typical durations falling between 20 and 50 seconds. These events are thought to be associated with the collapse of a star several times the sun's mass and the resulting birth of a new black hole. Both scenarios give rise to powerful jets that propel matter at nearly the speed of light in opposite directions. As they interact with matter in and around the star, the jets produce a spike of high-energy light. A detailed study of GRB 111209A, which erupted on Dec. 9, 2011, and continued to produce high-energy emission for an astonishing seven hours, making it by far the longest-duration GRB ever recorded.Another event, GRB 101225A, exploded on Christmas Day in 2010 and produced high-energy emission for at least two hours. Subsequently nicknamed the \"Christmas burst,\" the event's distance was unknown, which led two teams to arrive at radically different physical interpretations. One group concluded the blast was caused by an asteroid or comet falling onto a neutron star within our own galaxy. Another team determined that the burst was the outcome of a merger event in an exotic binary system located some 3.5 billion light-years away.Using the Gemini North Telescope in Hawaii, a team led by Andrew Levan at the University of Warwick in Coventry, England, obtained a spectrum of the faint galaxy that hosted the Christmas burst. This enabled the scientists to identify emission lines of oxygen and hydrogen and determine how much these lines were displaced to lower energies compared to their appearance in a laboratory. This difference, known to astronomers as a redshift, places the burst some 7 billion light-years away. Levan and his colleagues also examined 111209A and the more recent burst 121027A, which exploded on Oct. 27, 2012. All show similar X-ray, ultraviolet and optical emission and all arose from the central regions of compact galaxies that were actively forming stars. The astronomers conclude that all three GRBs constitute a hitherto unrecognized group of \"ultra-long\" bursts.To account for the normal class of long GRBs, astronomers envision a star similar to the size sun's size but with many times its mass. The mass must be high enough for the star to undergo an energy crisis, with its core ultimately running out of fuel and collapsing under its own weight to form a black hole. Some of the matter falling onto the nascent black hole becomes redirected into powerful jets that drill through the star, creating the gamma-ray spike, but because this burst is short-lived, the star must be comparatively small. Because ultra-long GRBs persist for periods up to 100 times greater than long GRBs, they require a stellar source of correspondingly greater physical size. Both groups suggest that the likely candidate is a supergiant, a star with about 20 times the sun's mass that still retains its deep hydrogen atmosphere, making it hundreds of times the sun's diameter.Watch this video on YouTube. || ",

            "title": "Fermi Proves Supernova Remnants Produce Cosmic Rays",
            "description": "A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of Fermi's primary mission goals.Cosmic rays are subatomic particles that move through space at nearly the speed of light. About 90 percent of them are protons, with the remainder consisting of electrons and atomic nuclei. In their journey across the galaxy, the electrically charged particles become deflected by magnetic fields. This scrambles their paths and makes it impossible to trace their origins directly.Through a variety of mechanisms, these speedy particles can lead to the emission of gamma rays, the most powerful form of light and a signal that travels to us directly from its sources.Two supernova remnants, known as IC 443 and W44, are expanding into cold, dense clouds of interstellar gas. This material emits gamma rays when struck by high-speed particles escaping the remnants.Scientists have been unable to ascertain which particle is responsible for this emission because cosmic-ray protons and electrons give rise to gamma rays with similar energies. Now, after analyzing four years of data, Fermi scientists see a gamma-ray feature from both remnants that, like a fingerprint, proves the culprits are protons.When cosmic-ray protons smash into normal protons, they produce a short-lived particle called a neutral pion. The pion quickly decays into a pair of gamma rays. This emission falls within a specific band of energies associated with the rest mass of the neutral pion, and it declines steeply toward lower energies. Detecting this low-end cutoff is clear proof that the gamma rays arise from decaying pions formed by protons accelerated within the supernova remnants.In 1949, the Fermi telescope's namesake, physicist Enrico Fermi, suggested that the highest-energy cosmic rays were accelerated in the magnetic fields of interstellar gas clouds. In the decades that followed, astronomers showed that supernova remnants were the galaxy's best candidate sites for this process.?A charged particle trapped in a supernova remnant's magnetic field moves randomly throughout it and occasionally crosses through the explosion's leading shock wave. Each round trip through the shock ramps up the particle's speed by about 1 percent. After many crossings, the particle obtains enough energy to break free and escapes into the galaxy as a newborn cosmic ray. The Fermi discovery builds on a strong hint of neutral pion decay in W44 observed by the Italian Space Agency's AGILE gamma-ray observatory and published in late 2011.Watch this video on YouTube. || ",

            "title": "RXTE Detects 'Heartbeat' Of Smallest Black Hole Candidate",
            "description": "Data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite has identified a candidate for the smallest-known black hole. The evidence comes from a specific type of X-ray pattern — nicknamed a \"heartbeat\" because of its resemblance to an electrocardiogram — that until now has been recorded in only one other black hole system. Named IGR J17091-3624 after the astronomical coordinates of its sky position, the binary system pairs a normal star with a black hole that may weigh less than three times the sun's mass, near the theoretical boundary where black-hole status first becomes possible. Flare-ups occur when gas from the normal star streams toward the black hole and forms a disk around it. Friction within the disk heats the gas to millions of degrees, which is hot enough to radiate X-rays.The record-holder for ubiquitous X-ray variability is another black hole binary named GRS 1915+105. This system is unique in displaying more than a dozen highly structured patterns — typically lasting between seconds and hours — that scientists distinguish by Greek-letter names. Seven of these patterns are now seen in IGR J17091, including the so-called rho-class oscillations that astronomers describe them as the \"heartbeat\" of black hole systems.It's thought that strong magnetic fields near the black hole's event horizon eject some of the gas into dual, oppositely directed jets that blast outward at nearly the speed of light. The peak of its heartbeat emission corresponds to the emergence of the jet. Changes in the X-ray spectrum observed by RXTE during each beat in GRS 1915 reveal that the innermost region of the disk emits enough radiation to push back the gas, creating a strong outward wind that staunches the inward flow, briefly starving the black hole and shutting down the jet. This corresponds to the faintest emission. Eventually the inner disk gets so bright and so hot that it essentially disintegrates and plunges toward the black hole, re-establishing the jet and beginning the cycle anew. In GRS 1915+105, which at 14 solar masses is by for the more massive of the two, this cycle can take as little as 40 seconds. In IGR J17091, the emission can be 20 times fainter than GRS 1915, and the heartbeat cycle can occur up to eight times faster.Download the animations here. || ",

The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles — cosmic rays. The emissions are likely the result of accelerated protons interacting with nearby gas clouds, but other possibilities have not been eliminated.

            "description": "During the Lunar Reconnaissance Oribiter's (LRO) Commissioning Phase, the high resolution Narrow Angle Camera (NAC) on the LRO Camera (LROC) instrument captured this 0.8-meter per pixel scale (angular resolution) two-image mosaic of Shackleton Crater on the moon's south pole. Many more images of this area will be obtained by the NAC over the coming months as the lunar south pole emerges from the shadows of winter. At meter scales, the geology of this region reminds us that the polar regions of the Moon are still waiting to be explored. The rim of Shackleton crater is a prime candidate for future human exploration due to its proximity to permanently shadowed regions and nearby peaks that are illuminated for much of the year.Last year, Japan's Selene and India's Chandrayaan spacecraft gave us our first high resolution look at the lunar south pole, which includes Shackleton crater. For its size, Shackleton has an exceptionally deep and rugged interior. Usually craters fill in with time as their walls slump and material from afar is thrown in by distant impacts. Much of Shackleton's rim appears rounded and is peppered with smaller craters, indications of a relatively ancient age. Right now it is not clear if Shackleton crater is relatively old or young. This NAC image reveals a shelf on the southeast flank of the crater that is more than two kilometers across and perfectly suitable for a future landing. The extreme Sun angle exaggerates the apparent roughness, however if you look closely at this scale any area that is between small craters could be good candidates for a potential landing site. || ",
