Astronomers have discovered the biggest explosion seen in the universe, originating from a supermassive black hole. The blast came from a black hole in a cluster of galaxies 390 million light-years away. The explosion was so large it carved out a crater in hot gases that could hold 15 Milky Ways. Astronomers used NASA’s Chandra X-Ray Observatory to make the discovery along with a European space observatory and ground telescopes. They believe the explosion came from the heart of Ophiuchus cluster of thousands of galaxies: a large galaxy at the center contains a colossal black hole. Black holes don’t just draw matter in, they also blast out jets of materials and energy. Chandra’s images of Ophiuchus galaxy cluster revealed an unusual curved edge due to an eruption given the amount of energy, that would have been needed to curve out such a large cavity in the gas. The two space observatories, along with radio data from telescopes in Australia and India confirmed that the curvature was, indeed, part of a cavity.
