Black hole 100,000 times bigger than sun discovered near center of Milky Way

A new kind of black hole has been found at the centre of the Milky Way – a find that may help explain the evolution of the phenomena. In research conducted by Japanese astronomers using the ALMA Observatory in northern Chile, a black hole 100,000 times the size of our sun was found within a molecular gas cloud. Its relatively small size means that it is the first to be identified as an

intermediate-mass black hole (IMBH). Professor Tomoharu Oka of Japan’s Keio University believes that black holes with masses greater than a million solar masses are at the centre of all galaxies and are essential to their growth. The origins of a supermassive black hole, however, remain a mystery. “One possible scenario is IMBHs – which are formed by the runaway coalescence of stars in young compact star clusters – merge at the centre of a galaxy to form a supermassive black hole,” said Prof Oka.
