A black hole 4000 times the size of the one at the centre of the Milky Way (above) has been found in a galaxy which is just a quarter of the size of our host galaxy, report astronomers from the University of Texas.

The galaxy NGC 1277, located 250 million light years from earth, is a fraction of the size of our Milky Way. Existing theories are founded on the belief that black holes and their galaxies evolve in tandem, their size directly related to one another.

Judging from this new discovery, though, it might be time to redefine those theories. Science is only ever what we know yet, so it seems that, in this case, we just don’t know quite as much right now as we thought we did.
