05-06-1998
A recently detected cosmic gamma ray burst released a
hundred times more energy than previously theorized, making it the most
powerful explosion since the creation of the universe in the Big Bang.
"For about one or two seconds, this burst was as luminous
as all the rest of the entire universe," said Caltech professor George
Djorgovski, one of the two principal investigators on the team from t...

Gamma-ray bursts: upping the ante. (Gamma Ray Observatory data)
Science News
; Like cosmic flashbulbs, gamma-ray bursts are intense flares that last just a few seconds and then vanish, usually forever. The origins and properties of these celestial bursts have remained a mystery since their discovery 20 years ago. Early results from NASA's Gamma Ray Observatory add a new twist
