WASHINGTON (CyHAN)- Over the past decade, NASA's Swift Gamma-ray Burst Explorer has proven itself to be one of the most versatile astrophysics missions ever flown.
Known as a gamma-ray burst, light from the rare, high-energy explosion traveled for 12.1 billion years before it was detected and observed by a telescope, ROTSE-IIIb, owned by Southern Methodist University, Dallas.
Berger's team knew about the explosion after a gamma-ray burst from the collision was detected on June 3 by NASA's Swift satellite.
The most powerful explosions in the universe are brilliant flashes of light called gamma-ray bursts. If you happened to fly through the neighborhood of a gamma-ray burst, you couldn't miss the flare--it would be brighter than a million trillion suns.
Scientists believe the pattern of trilobite extinctions at that time matched the expected effects of a nearby gamma-ray burst. Gamma-ray bursts, or GRBs,are the most powerful cosmological explosions known.
The first gamma-ray burst recorded was detected on July 2 1967 by the Vela satellites.
The most powerful explosion ever witnessed - a gamma-ray burst 12billion light years away - released in one second almost as much energy as all the stars of the universe, astronomers said yesterday.
"This means that it is quite likely that every neutron star that merges actually creates a gamma-ray burst, but we only see a small fraction of them because the jet doesn't line up all that often."
