Astronomers pursue renegade supermassive Black Hole

Washington, May 12 (IBNS): Supermassive black holes are generally stationary objects, sitting at the centers of most galaxies.

Black Hole makes material wobble around it

California, July 13 (IBNS) The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole.

Clandestine Black Hole may represent new population

Washington, June 27 (IBNS) Astronomers have combined data from NASA’s Chandra X-ray Observatory, the Hubble Space Telescope and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to conclude that a peculiar source of radio waves thought to be a distant galaxy is actually a nearby binary star system containing a low-mass star and a black hole.

X-ray echoes of a shredded star provide close-up of 'killer' Black Hole

California, June 23 (IBNS): Some 3.9 billion years ago in the heart of a distant galaxy, the intense tidal pull of a monster black hole shredded a star that passed too close. When X-rays produced in this event first reached Earth on March 28, 2011, they were detected by NASA's Swift satellite, which notified astronomers around the world. Within days, scientists concluded that the outburst, now known as Swift J1644+57, represented both the tidal disruption of a star and the sudden flare-up of a previously inactive black hole.
