CAPE CANAVERAL, Fla. (AP) – Astronomers have discovered the biggest explosion seen in the universe.

Scientists reported Thursday that the blast likely 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 the hot gas that could hold 15 Milky Ways. That’s five times greater than the previous record-holder.

Astronomers used NASA’s Chandra X-Ray Observatory to make the latest discovery, along with a European space observatory and ground telescopes.

The first hint of the giant explosion came in 2016. It’s believed to be over by now.
