19 Nov 2018, 16:00 UTC The VISIR instrument on ESO’s Very Large Telescope has captured this stunning image of a newly discovered massive triple star system. Nicknamed Apep after an ancient Egyptian deity, this may be the first ever gamma-ray burst progenitor found. Next Previous
15 Nov 2018, 19:00 UTC The most luminousLuminousIn astronomy, luminosity is an actual unit. It's the amount of energy given off by a star or galaxy, or any other object -- over a specific period of time. "Brightness," in astronomy, is how apparently bright an object appears to an observer. Brightness goes down with distance. Luminosity does not. galaxy in the universe has been caught in the act of stripping away nearly half the mass from at least three of its smaller neighbors, according to a new study published in the journal Science. The light from this galaxy, known as W2246-0526, took 12.4 billion years to reach us, so we are seeing it as it was when our universe was only about a tenth of its present age.New observations with the Atacama Large Millimeter/submillimeter Array (ALMA)Atacama Large Millimeter/submillimeter Array (ALMA)Funded by the U.S. National Science Foundation and its international partners (NRAO/ESO/NAOJ), ALMA is among the most complex and powerful astronomical observatories on Earth or in space. The telescope is an array of 66 high-precision dish antennas in northern Chile. See more here reveal distinct streamers of material being pulled from three smaller galaxies and flowing into the more massive galaxy, which was discovered in 2015 ... Next Previous

ALMA (Atacama Large Millimetre/Submillimetre Array) 12 Dec 2018, 13:58 UTC Astronomers have already cataloged nearly 4,000 exoplanets in orbit around distant stars. Though we have learned much about these newfound worlds, there is still much we do not know about the steps of planet formation and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered, including so-called hot Jupiters, massive rocky worlds, icy dwarf planets, and – hopefully someday soon – distant analogs of Earth.
ESO Top News 12 Dec 2018, 13:00 UTC While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large Telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.
NASA's Jet Propulsion Laboratory News and Features 11 Dec 2018, 20:12 UTC NASA's InSight lander isn't camera-shy. The spacecraft used a camera on its robotic arm to take its first selfie - a mosaic made up of 11 images. This is the same imaging process used by NASA's Curiosity rover mission, in which many overlapping pictures are taken and later stitched together. Visible in the selfie are the lander's solar panel and its entire deck, including its science instruments.
Carnegie Science 11 Dec 2018, 14:43 UTC New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. Led by Carnegie astronomer Chris Burns, the team’s findings are published in The Astrophysical Journal.
HubbleSite NewsCenter -- Latest News Releases 10 Dec 2018, 21:15 UTC Giacconi leaves a legacy that will endure for generations. The worldwide astronomical community mourns the loss of Riccardo Giacconi, the first permanent director of the Space Telescope Science Institute (STScI) in Baltimore, Maryland.

Centauri Dreams 12 Dec 2018, 18:10 UTC The science return from OSIRIS-REx has been surprisingly swift as the spacecraft returns data on near-Earth asteroid 101955 Bennu. We’re aided here by the timing, as early results are being discussed at the ongoing conference of the American Geophysical Union (AGU) in Washington, DC. The imagery we’ve received of Bennu’s surface has scientists buzzing.
The Planetary Society Blog 12 Dec 2018, 16:23 UTC China’s Chang’e-4 lunar mission, the first-ever soft-landing endeavor on the lunar farside, launched successfully on 8 December at 02:23 Beijing time (7 December at 18:23 UTC) via a Long March 3B rocket from Xichang Satellite Launch Center. The launch carried a lander and a rover toward the Moon. On 12 December at 8:45 Beijing time (16:45 UTC), the spacecraft arrived in lunar orbit, preparing for a landing in early January.
Bad Astronomy 12 Dec 2018, 14:00 UTC Holy barsoomian impact! What a beauty! For scale, the crater is about 3 kilometers wide. As you can see, though, it’s wonky. The right (east) side looks fine and circular, but things go off the rails a bit as you circle around to the left (west). The northwest side is significantly flattened, and the inside of the crater wall has that wedge-shaped structure inside it all the way down to the crater floor. The floor itself looks flat, too (though that isn’t uncommon).
SciTech Daily 12 Dec 2018, 01:58 UTC 3C196.1 is a massive elliptical galaxy, the brightest member of a cluster of galaxies about three billion light-years away that is notable for its strong X-ray and radio emission. The radiation is a characteristic signature of accretion processes around a supermassive black hole at the galaxy’s nucleus. Supporting this interpretation is the galaxy’s disturbed shape, which indicates the galaxy has undergone a recent merger, perhaps triggering such accretion onto the black hole and thus powering the emission.
Astronomy Now 11 Dec 2018, 22:44 UTC NASA’s InSight Mars lander, using a camera on the spacecraft’s robot arm, has snapped a series of 11 images allowing engineers to assemble a selfie showing the probe, solar wings extended, resting on a flat, obstruction-free plain – exactly the sort of landing site needed to meet the mission’s science objectives.
