Global News, a Canadian news outlet, reported that astronomers detected an explosion over fifteen times the size of our galaxy. This makes it the biggest blast ever recorded.
The massive explosion occurred hundreds of millions of light-years away, where a supermassive black hole emitted large amounts of energy and matter while devouring a galaxy, blowing a hole in space that’s 2.58 million light-years across. It wiped out trillions of stars and tore through the surrounding galaxies. Researchers spotted the hole from the colossal gap it left in the middle of a cluster of galaxies.
The blast occurred in the Ophiucus cluster, a collection of galaxies some 390 million light-years away. It’s unclear exactly when the explosion happened, but researchers say it was definitely millions of years ago.
