Biggest-ever explosion in universe detected

Mass Equivalent To 300 Suns Sucked Into Black Hole

By Chidanand Rajghatta TIMES NEWS NETWORK


Washington: Astronomers have discovered the most powerful eruption of energy yet observed in the universe. The event, detected by the Chandra X-ray observatory operated by NASA, has been generated by a supermassive black hole. It has been going on for 100 million years and has been devouring vast amounts of material—the equivalent of 300 million suns—from its neighbourhood.
    Describing the event, NASA scientists said the explosion was caused by a gravitational energy release during which huge amounts of matter fell towards a black hole. Most of the matter was swallowed, but some of it was violently ejected. They are not sure where such enormous amounts of matter came from. One possibility is a host galaxy cooled catastrophically and was swallowed by the black hole. Another is that another black hole fell into an existing black hole.
    The huge eruption was seen in a Chandra image of the hot, X-ray emitting gas of a galaxy cluster called MS 0735.6+7421 released by NASA. Two vast cavities extend away from the super massive black hole in the cluster's central galaxy. The cavities are so large—about 650,000 light years across—that they indicate the power of the eruption.
    NASA said in a statement that Chandra has discovered evidence of similar outbursts in the form of other X-ray cavities in galaxy clusters, but the cavities in MS 0735 "are easily the largest and most powerful seen to date''. To create such an enormous eruption, the supermassive black hole must have swallowed about 300 million solar masses of gas in the last hundred million years, the space agency suggested.
    "I was stunned to find that a mass of about 300 million suns was swallowed,'' Brian McNamara of Ohio University, lead author of the study about the discovery reported in Nature magazine, said.
    How big is it?
This big bang has been going on for 100 million years. It's the most powerful explosion we know of
How did it happen?
A hot galaxy cooled catastrophically and was swallowed by the black hole or another black hole fell into this black hole
