Stellar Pair Shot Out from Its Birthplace:
Astronomers studying data from the National Science Foundation's Very Long Baseline Array (VLBA) and other telescopes have concluded that a binary pair of stars forming an energetic microquasar was blasted out of the cluster in which it was born by a supernova explosion some 1.7 million years ago. This is the first time that a fast-moving stellar pair has been tracked back to a specific star cluster.
GR17, the 17th International Conference on General Relativity and Gravitation
Listed among the program speakers is Stephen Hawking who, after nearly 30 years of arguing that a black hole destroys everything that falls into it, will be coming to announce that he was wrong. It seems that black holes may after all allow information within them to escape. Hawking will speak on this at the GR17 conference in Ireland this week.
Chandra looks over a cosmic four-leaf clover
NASA’s Chandra X-ray Observatory has uncovered evidence that a single star in a foreground galaxy may have magnified X-rays coming from a rare quadruple quasar. About 11 billion light years from Earth, the Cloverleaf quasar is a single object that appears as four images. The Marshall Center manages the Chandra program.
