Searching for the end of the cosmic dark ages with GMOS

A team of U.S. astronomers led by James Rhoads from the Space Telescope Science Institute, reports the discovery of extremely high rates of star formation in one of the most distant known galaxies in the universe.

Chandra catches early phase of cosmic assembly

A NASA Chandra X-ray Observatory image has revealed a complex of several intergalactic hot gas clouds in the process of merging. The superb Chandra spatial resolution made it possible to distinguish individual galaxies from the massive clouds of hot gas...

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.

NASA Infrared Camera Helps Surgeons Map Brain Tumors

Using an infrared video camera developed by researchers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., surgeons are testing thermal imaging and image processing to see if they can create useful maps of brain tumors.
