In its first five years in orbit, NASA's Swift satellite has given astronomers more than they could have hoped for. Its discoveries range from a nearby nascent supernova to a blast so far away that it happened when our universe was only 5 percent of its present age. Swift primarily studies gamma-ray bursts (GRBs) -- the biggest and most mysterious explosions in the cosmos. On April 13, the spacecraft's "burst-o-meter" cataloged its 500th GRB. "On the one hand, it's just a number, but on the...

PSU -- It came from the edge of the visible universe, the most distant explosion ever detected. In this week's issue of Nature, scientists at Penn State University and their U.S. and European colleagues discuss how this explosion, detected on 4 September 2005, was the result of a massive star collapsing into a black hole. The explosion, called a gamma-ray burst, comes from an era soon after stars and galaxies first formed, about 500 million to 1 billion years after the Big Bang. The...

LONDON (Reuters) - Three international teams of astronomers said on Wednesday they have detected the most distant gamma ray burst ever observed in the early Universe. The cosmic explosion, a gamma ray burst (GRB) called GRB 050904, was detected by astronomers in the United States, Japan and Italy last September using NASA's Swift satellite. A gamma ray burst is the most distant and powerful type of explosion known to astronomers. It can last from a few milliseconds to several...
