|The biggest and brightest cosmic explosion ever witnessed was captured by orbiting telescopes last spring, astronomers have said. |
Branded ‘the monster’ by scientists, lucky for us on Earth, the huge gamma ray explosion happened in a far off galaxy 3.7 billion light-years away.
"This burst was a once-in-a-century cosmic event," Nasa astrophysics chief Paul Hertz said at a news conference Thursday.
A gamma ray burst happens when a massive star dies, collapses into a black hole, explodes in what's called a supernova and ejects energetic radiation. A planet caught in one of these bursts would lose its atmosphere instantly and be left a burnt cinder, scientists say.
