10 Mar 2017, 14:20 UTC This beautiful Hubble image reveals a young super star cluster known as Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, yet home to one of the largest stars ever discovered. Next Previous
8 Mar 2017, 11:00 UTC Astronomers have used ALMA to detect a huge mass of glowing stardust in a galaxy seen when the Universe was only four percent of its present age. This galaxy was observed shortly after its formation and is the most distant galaxy in which dust has been detected. This observation is also the most distant detection of oxygen in the Universe. These new results provide brand-new insights into the birth and explosive deaths of the very first stars. Next Previous

NASA Breaking News 23 Mar 2017, 20:18 UTC Expedition 50 astronauts will conduct up to three spacewalks outside the International Space Station (ISS) in late March and early April to prepare for the future arrival of U.S. commercial crew spacecraft and upgrade station hardware. The first spacewalk remains on schedule for Friday, March 24. A second spacewalk has been rescheduled to Thursday, March 30, and a third spacewalk now is scheduled for Thursday, April 6.

During the spacewalk, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections on the Pressurized Mating Adapter-3 to prepare for its robotic move Sunday, March 26.
Starts With A Bang! 24 Mar 2017, 14:06 UTC 13.8 billion years ago, the Universe as we know it came into existence. Today, the part we can observe is 46 billion light years in radius, having grown tremendously thanks to the expansion of the Universe. But if we extrapolate that backwards, we find that the Universe couldn’t have been infinitely small at the moment of its birth, but rather was a finite size at all finite times.

EarthSky Blog 24 Mar 2017, 10:00 UTC The animation above shows a new 3-D rendering of space dust, as viewed in a several-thousand-light-year loop through and out of the flat plane of our Milky Way galaxy. It’s part of a new study by scientists at Berkeley Lab, published March 22, 2017 in the peer-reviewed Astrophysical Journal. Why a study of space dust? For one thing, as these study authors explained in a statement: Consider that the Earth is just a giant cosmic dust bunny — a big bundle of debris amassed from exploded stars. We Earthlings are essentially just little clumps of stardust, too, albeit with very complex chemistry. So space dust has intrinsic interest. However, the clouds of space dust in our Milky Way galaxy can also be problematic for astronomers. Dust can dim, or obscure, the light of stars and galaxies beyond. Lead author of the new study is Edward F. Schlafly, a Hubble Fellow at Berkeley Lab. He explained: The light from … distant galaxies travels for billions of years before we see it, but in the last thousand years of its journey toward us a few percent of that light is absorbed and scattered by dust in our own galaxy. We need to ...
