Saturn's Shadow and Titan's Glow Shed Light on a Complex System

The Cassini spacecraft, which began its tour of the Saturn system just over a month ago, has detected lightning and a new radiation belt at Saturn, and a glow around the planet's largest moon, Titan.

Gamma-ray burst of December 3 was a new type of cosmic explosion

PASADENA, Calif.--Astronomers have identified a new class of cosmic explosions that are more powerful than supernovae but considerably weaker than most gamma-ray bursts. The discovery strongly suggests a continuum between the two previously-known classes of explosions...

Hubble Images Majestic Cousin of the Milky Way

Our Sun and solar system are embedded in a broad pancake of stars deep within the disk of the Milky Way galaxy. Even from a distance, it is impossible to see our galaxy's large-scale features other than the disk...

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.
