Biggest explosion since the Big Bang spotted: It nearly split a galaxy in two

In the Ophiuchus galaxy cluster, astronomers spotted the largest explosion in the universe, and that explosion consisted of energy equivalent to a billion supernovae as it made a 1.5 million-light-year-wide bubble. The outburst, which began from a supermassive black hole and contradicted existing models of galaxy clusters, can help provide insights into them. The term is metaphorical, as the Big Bang wasn’t an explosion in the traditional sense but the origin of the universe as we know it.
