The ultramassive black hole, one of just four ever observed, is more than 30 billion times the mass of the Sun, a new study said.
It is the first black hole ever observed using a phenomenon called gravitational lensing, in which light travelling towards us from a distant galaxy appears to magnify and bend inwards, giving away the presence of a dark giant.
James Nightingale, an astronomer at the UK's Durham University and the study's lead author, told AFP the process was "similar to shining light through the base of a wine glass".
There are currently around 500 known gravitational lenses -- at least one of which we now know is a supermassive black hole.
But "the landscape is about to dramatically change," Nightingale said.
The European Space Agency's Euclid mission, planned to launch into space in July, will open a "big data era" for black hole hunters by creating a huge high resolution map of the universe, he said.
In the next six years Euclid could find 100,000 new gravitational lenses, which would potentially point towards thousands of previously hidden black holes, Nightingale added.

Title adjusted, thanks. I am reading around methods of measurement and some of the other black holes discovered.Vanadium 50 said:Is it the largest or one of the largest?
