RX J1242.6-1119A , often abbreviated as RX J1242-11 , is a galaxy in the constellation Virgo at a distance of approximately 200 Mpc (approximately 650 million light years ). At the beginning of 2004 it was possible to observe in this galaxy for the first time how a supermassive black hole withdrew and incorporated matter from a relatively close star . The star was literally torn apart by the great gravitational and tidal effects . The name is derived from RX J1242.6-1119, the name of an X-ray source identified by ROSAT as a pair of galaxies.
