Astronomers have detected what they describe as the biggest known explosion in the universe since the Big Bang. The blast came from a supermassive black hole in the distant Ophiuchus galaxy cluster, the cause of which has only recently been established with the use of giant radio telescopes. Professor Melanie Johnston-Hollitt is a co-author of the study and the director of the one of the radio telescopes used on the project. Speaking from Perth, Australia she told 大象传媒 Newsday just how big the bang was.
