| Why super massive black holes consume less material than expected Posted: 29 Aug 2013 11:51 AM PDT Astronomers have solved the mystery of why most super massive black holes have such a low accretion rate -- that is, they feed on very little of the available gases, instead acting as if they are on a severe diet. |
| NASA's Chandra Observatory catches giant black hole rejecting material Posted: 29 Aug 2013 11:23 AM PDT Astronomers using NASA's Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes. |
| NASA's Hubble sees a cosmic caterpillar Posted: 29 Aug 2013 09:34 AM PDT The light-year-long knot of interstellar gas and dust, seen in a new Hubble photo, resembles a caterpillar on its way to a feast. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this 'wanna-be' star and sculpting the gas and dust into its long shape. |
