OT:Satellite Detects Massive Explosion

Wow!:Q ,instresting ,thanks🙂

Astronomers using NASA's Swift satellite said yesterday that they have detected the most distant explosion ever discovered in the universe, the collapse into a black hole of a massive star about 12.6 billion light-years from Earth
 
Nice 1!!!

The massive blast, known as a gamma ray burst, lasted 200 seconds and was detected Sept. 4 by the Earth-orbiting Swift, which relayed the sighting to astronomers who used ground-based telescopes to observe the burst and its afterglow. Because the explosion was so distant, light from it is only now reaching Earth.
