New Cause For Supernova Explosion IdentifiedGarching, Germany (SPX) May 20, 2010 Supernovae, gigantic stellar explosions, are not only used as cosmic yardsticks by cosmologists, they are also important chemical element factories in our Universe. So far, astrophysicists know of two physical processes giving rise to these bursts: one is the core collapse of a massive star at the end of its lifetime, the other the thermonuclear detonation of an old white dwarf star. An international team of researchers, including scientists from the Max Planck Institute for Astrophysics, have now ... read more |

Boston MA (SPX) May 13, 2010Using observations with NASA's Chandra X-ray Observatory and ESA's XMM-Newton, astronomers have announced a robust detection of a vast reservoir of intergalactic gas about 400 million light years from Earth. This discovery is the strongest evidence yet that the "missing matter" in the nearby Universe is located in an enormous web of hot, diffuse gas. This missing matter - which is differen ... more  
Moffett Field CA (SPX) May 12, 2010The 2010 Astrobiology Science Conference recently was held deep in the heart of Texas, near NASA's Johnson Space Center. The famous line "Houston, we've had a problem" could've been a tag line for the conference - except the "problem" in this case was not a wounded Apollo 13 spacecraft, but the puzzling and ongoing search for answers about the origin and evolution of life on Earth and the possib ... more 
Washington DC (SPX) May 12, 2010A heavy runaway star is rushing away from a nearby stellar nursery at more than 250,000 miles an hour, a speed that will get you to the Moon and back in two hours. The runaway is the most extreme case of a very massive star that has been kicked out of its home by a group of even heftier siblings. The homeless star is on the outskirts of the 30 Doradus nebula, a raucous stellar breeding gro ... more |

Black Holes Are The Gas Blowers Of The UniverseGarching, Germany (SPX) May 12, 2010 Supermassive black holes with the mass of many millions of stars have been detected at the centre of many large galaxies. A super-massive black hole acts like a lurking "monster" at the centre of the galaxy which swallows the surrounding material through the intensity of its gravitational pull. X-ray observations indicate that a large amount of energy is produced by the in-fall of matter into a black hole, and ejected in powerful jets. Astronomers from the Max Planck Institute for Extraterrestrial ... read more |
