CosmicRami<p>Astronomers: Omega Centauri - a massive globular cluster orbiting our Galaxy - likely has a 20,000 solar mass black hole in its core.</p><p>The globular cluster, which contains approx. 10 million stars is thought to be the remnant core of a former dwarf galaxy, now cannibalised by the Milky Way. </p><p>These new findings might provide the 'missing link' between stellar-mass black holes and supermassive black holes. </p><p>I had a chat with The University of Queensland Dr Holger Baumgardt who played a direct role in providing the theoretical modelling and investigations into the stellar velocities around the monster black hole.
