Australian astronomers find black hole as big as 20 billion suns

Australian astronomers have discovered a supermassive black hole that's as big as 20 billion of our suns.

Australian astronomers have found the fastest-growing black hole in the known universe.

The so-called supermassive black hole is more than 12 billion light years away and thought to be the size of 20 billion of our suns.

And it's growing so fast, it's able to devour the mass equivalent to our sun every two days.

Dr Christian Wolf and his team at Australian National University's Research School of Astronomy and Astrophysics were behind the discovery.

It was detected at the ANU Siding Spring Observatory.

Dr Wolf said it's "actually remarkably hard to find these very fast-growing and very massive black holes because they are rare and (it's) not easy to tell them apart from other stars in our Milky Way".

The supermassive black hole is so powerful, that if it were at the centre of the Milky Way, all life on earth would be impossible.
