Australian astronomers have discovered the fastest-growing black hole ever found in deep space.
The hole devours mass equivalent to the the sun every two days.
The black hole is more than 12 billion light-years away and is currently the size of 20 billion suns.
"The black hole is growing so rapidly that it's shining thousands of times more brightly than an entire galaxy due to all of the gases it sucks in daily that causes lots of friction and heat," Dr Christian Wolf from the Australian National University told 7 News
He said if the black hole were at the centre of the Milky Way galaxy it would appear 10 times brighter than a full moon.
"It would appear as an incredibly bright pin-point star that would almost wash out all of the stars in the sky," Dr Wolf told 7 News.
The discovery was made using a spectrograph at the Australian National University's Research School of Astronomy and Astrophysics.
