The black hole lies in the spiral galaxy NGC 7172, located about 110 million light-years away from Earth in the ancient, but small constellation Piscis Austrinus. The dark dust passes through the centre of the galaxy, obscuring its luminous heart. This makes NGC 7172 appear to be nothing more than a normal spiral galaxy when viewed from…
