Supermassive black hole (SMBH), a black hole more than one hundred thousand times the mass of the Sun. Nearly every large galaxy has a supermassive black hole at its centre. Active galactic nuclei, such as Seyfert galaxies and quasars, are powered by supermassive black holes. The largest supermassive black hole is in the galaxy cluster Abell 1201 and has a mass thirty billion times that of the Sun. Sagittarius A*, the supermassive black hole at the centre of the Milky Way Galaxy, has a mass fou...
