Scientists at Durham University have discovered an ultramassive black hole around 33 billion times the mass of the Sun.
The gargantuan black hole, which is somewhere in space, is said to be one of the biggest ever found. The team described its findings, which were published in the journal Monthly Notices of the Royal Astronomical Society as "extremely exciting".
Dr James Nightingale of the Department of Physics at Durham University and lead author of the paper said: "This particular black hole, which is roughly 30 billion times the mass of our Sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become, so it is an extremely exciting discovery.
