Researchers detected biggest explosion since Big Bang:
Researchers have detected evidence of a colossal explosion in space which is five times bigger than anything observed before. The huge release of energy is expected to have occurred from a supermassive black hole which is located around some 390 million light-years from Earth. Also, the scientists stated that the explosion might have left a giant dent in the Ophiuchus galaxy cluster.
Ophiuchus galaxy cluster:
Ophiuchus galaxy cluster is a large galaxy that contains a supermassive black hole. The source of the gigantic eruption to jets has carved out a large cavity in the hot gas. The amount of energy required to create the cavity in Ophiuchus far exceeded the previous record holder, a cluster known by the designation MS 0735+74. The cluster contains thousands of individual galaxies intermingled with hot gas and dark matter.
US and European X-ray telescopes found a curved edge to it. It is suspected that it might be the wall of a cavity that had been sculpted in its plasma by emissions from a gargantuan black hole in one of the core galaxies. The theory was confirmed by a new low-frequency telescope data from the Murchison Widefield Array (MWA) in Australia and the Giant Metrewave Radio Telescope (GMRT) in India.
