NASA will hold a media teleconference Wednesday, May 26, at 1 p.m. EDT, to discuss new results from the Swift satellite's survey of active black holes. Swift's hard X-ray survey detects supermassive black holes in the hearts of nearby galaxies that are absorbing gas and emitting energy. The survey has uncovered dozens of previously unknown active black holes that were hidden from observations at other wavelengths. These discoveries confirm theoretical ideas about how black hole activity is...

A specialized camera on a telescope operated by U.K. astronomers from Liverpool has made the first measurement of magnetic fields in the afterglow of a gamma-ray burst (GRB). The result is reported in the Dec. 10 issue of Nature magazine by the team of Liverpool John Moores University (LJMU) astronomers who built and operate the telescope and its unique scientific camera, named RINGO. The burst occurred January 2, 2009. NASA's Swift satellite observed its position and immediately notified...

Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing. A single gamma-ray burst (GRB) can easily outshine an entire galaxy containing hundreds of billions of stars. Powerful telescopes can see them from clear across the Universe. And because the deeper you look into space, the farther back in time you see, astronomers should be able to see GRBs from the...

For decades it was baffling. Out of the still night sky, astronomers peering through their telescopes would occasionally glimpse quick bursts of high-energy light popping off like flashbulbs at the far side of the universe. These bursts seemed impossibly powerful: to appear so bright from so very far away, they must vastly outshine entire galaxies containing hundreds of billions of stars. These explosions, called gamma ray bursts (GRBs), are by far the brightest and most energetic phenomena...

People of the 'Deep South' love a good story and they're about to get a doozy. It begins next week when researchers from 25 countries converge on Huntsville, Alabama, to share the latest findings on the biggest explosions since the Big Bang itself. The 6th Huntsville Gamma-ray Burst Symposium 2008 convenes Oct. 20th and the talking won't stop for four straight days. One speaker after another will take the audience on a wild ride from the edge of the observable Universe, where gamma-ray bursts...

GREENBELT, Md. (AP) -- The birth of a black hole has been captured for the first time, a NASA scientist said Monday. NASA's Swift orbiting observatory detected the gamma ray burst of the collision between two dense neutron stars about early Monday and pointed its visible light and X-ray telescopes at the collision about a minute later, said Neil Gehrels, lead scientist for the Swift mission. "The birth cry of a black hole is one way people like to put it," Gehrels said, adding the huge...
