Biggest explosion "since Big Bang" discovered by astronomers
It happened around 400 million years ago
The biggest explosion in the universe since the Big Bang has been discovered by astronomers.
The blast came from a supermassive black hole at the centre of a galaxy hundreds of millions of light-years away.
Scientists say it released five times more energy than the previous record holder.
Professor Melanie Johnston-Hollitt, from the Curtin University node of the International Centre for Radio Astronomy Research, said the event was extraordinarily energetic.
