Researchers from Durham University discover the black hole by using a phenomenon known as gravitational lensing, where they convert a nearby galaxy into a giant magnifying glass.
An ultramassive black hole around 33 billion times the mass of the sun has been discovered by UK astronomers.The team described its findings, published in the journal Monthly Notices of the Royal Astronomical Society, as"extremely exciting".
Lead author Dr James Nightingale, of the Department of Physics at Durham University, 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."
Ultramassive black holes are the most massive objects in the universe, at between 10 billion and 40 billion times the mass of the sun. Astronomers believe they can be found at the centre of all large galaxies such as the Milky Way, which includes our own solar system.Some believe they were formed from the extreme merger of massive galaxies billions of years ago when the universe was still young.
The researchers used a phenomenon known as gravitational lensing, where they took help from a nearby galaxy by converting it into a giant magnifying glass.This revealed the presence of the ultramassive black hole, a region where gravity's pull is so powerful that not even light can escape.
