Researchers say the blast is the biggest since the universe began. It occurred at the center of a galaxy cluster some 390 million light years away from Earth.
Astronomers have discovered the biggest explosion seen since the begining of the universe, originating from a super-massive black hole.
The blast, they said, is the biggest explosion seen since the Big Bang — the cosmologial model to describe a rapid expansion of matter and energy that created the observable universe. The explosion reportedly released five times more energy than the previous record holder.
The blast occurred at the center of the Ophiuchus cluster of galaxies, some 390 million light years away. The cluster is a conglomeration of thousands of galaxies, hot gas and dark matter bound together by gravity.
