| Smallest known galaxy with a supermassive black hole Posted: 17 Sep 2014 10:16 AM PDT Astronomers have discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. The finding suggests huge black holes may be more common than previously believed. |
| NASA chooses American companies to transport U.S. astronauts to International Space Station Posted: 17 Sep 2014 05:46 AM PDT U.S. astronauts once again will travel to and from the International Space Station from the United States on American spacecraft under groundbreaking contracts NASA announced Tuesday. The agency unveiled its selection of Boeing and SpaceX to transport U.S. crews to and from the space station using their CST-100 and Crew Dragon spacecraft, respectively, with a goal of ending the nation's sole reliance on Russia in 2017. |
| Violent origins of disc galaxies: Why Milky Way-like galaxies are so common in the universe Posted: 17 Sep 2014 04:31 AM PDT For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe. |
