Astronomers have discovered a supermassive black hole that appears to have grown to a ridiculous size.
Scientists had long believed that the growth of a supermassive black hole is closely linked to the growth of its parent galaxy meaning that one should generally remain proportional to the other.
This week however the discovery of a black hole containing ten percent of its host galaxy’s entire mass has turned this idea upside-down and left scientists scratching their heads.
“This is really unexpected and was found in a really small survey, so it can’t be that rare, unless we’re just extraordinarily fortunate,” said study co-author Professor Megan Urry.
The supermassive black hole in question, which measures a whopping 6.9 billion times the mass of the sun, is located in the distant galaxy CID-947 which formed two billion years after the Big Bang.
Most supermassive black holes are only 0.2 to 0.5 percent of the mass of their host galaxies.
