18 Feb 04 - X-ray data from Chandra, the European Space Agency's XMM-Newton, and the German Roengtensatellite (ROSAT) X-ray observatories provide direct evidence for the catastrophic destruction of a star that wandered too close to a supermassive black hole. The accompanying illustration (top) depicts how such an event may have occurred. A close encounter with another star put the doomed star (orange circle) on a path that took it near a supermassive black hole. The enormous gravity of the giant black hole stretched the star until it was torn apart. Because of the momentum and energy of the accretion process, only a few percent of the disrupted star's mass (indicated by the white stream) was swallowed by the black hole, while the rest of was flung away into the surrounding galaxy.
