The monster object is more than 11 times wider than the orbit of Neptune, the eighth planet in the Solar System.

It lies at the heart of a small lens-shaped galaxy called NGC1277, 220 million light years away in the constellation Perseus.

The black hole makes up an enormous 14pc of the galaxy's mass. Other black holes found at the centres of galaxies only account for around 0.1pc.

Black holes are formed from matter collapsing to the point where normal laws of physics break down.

Their gravity is so strong that space and time are distorted, and not even light can escape.

A description of the black hole, found by astronomers using the nine-metre Hobby-Eberly Telescope in Texas, appears in the journal 'Nature'.
