Astronomers have detected what they say is the biggest explosion in the universe that we have ever seen. It is the largest since the Big Bang.
Researchers say the blast took place 390 million light years away in a super massive black hole, leaving a 'crater' the size of 15 Milky Ways. They spotted the remnants of the blast in the distant galaxy by using some of the most powerful telescopes that we have!
So how big was this explosion?
Scientist Melanie Johnston-Hollitt compared it to a 20 billion-billion megaton TNT explosion going off every thousandth of a second - for 240 million years. In other words, "Huge".
