| River of hydrogen flowing through space observed Posted: 27 Jan 2014 01:44 PM PST Astronomers have discovered what could be a never-before-seen river of hydrogen flowing through space. This very faint, very tenuous filament of gas is streaming into the nearby galaxy NGC 6946 and may help explain how certain spiral galaxies keep up their steady pace of star formation. |
| Solving a 30-year-old problem in massive star formation Posted: 27 Jan 2014 11:17 AM PST Astrophysicists have found evidence strongly supporting a solution to a long-standing puzzle about the birth of some of the most massive stars in the universe. Young massive stars shine brightly in the ultraviolet, heating the gas around them, and it has long been a mystery why the hot gas doesn't explode outwards. Now, observations have confirmed predications that as the gas cloud collapses, it forms dense filamentary structures that absorb the star's ultraviolet radiation. |
| Exceptionally close stellar explosion discovered Posted: 27 Jan 2014 06:32 AM PST An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions. |
