Chinese space telescope to observe ‘big eaters’
China's new space telescope will probe many mysteries of the universe, including the belching "big eaters"-active galactic nuclei at the most remote edges of the universe. Scientists have discovered that almost every galaxy has a supermassive black hole with a mass several million to several billion times that of the Sun at its centre. With …

NASA detects supermassive black hole in distant galaxy
NASA's Hubble space telescope has detected a supermassive black hole that has been kicked out of the centre of a distant galaxy by what could be the awesome power of gravitational waves. Weighing more than one billion suns, the rogue black hole is the most massive black hole ever detected to have been kicked out …

Dwarf star found orbiting closest to black hole
Researchers have found evidence of a white dwarf star orbiting a likely black hole at a distance of only 961,000 km — just about 2.5 times the distance between the Earth and the Moon. In a tightest orbital dance ever witnessed for a black hole and a companion star, the star whips around the black …

Black hole found producing fuel for star formation
In a surprising discovery, astronomers have observed a black hole producing cold, star-making fuel from hot plasma jets and bubbles. The researchers found that powerful radio jets from the black hole — which normally suppress star formation — are stimulating the production of cold gas in the galaxy's extended halo of hot gas. This newly …

Black hole devouring star for a decade detected
Astronomers have detected a giant black hole that ripped apart a star and then gorged on its remains for an unusually long time about a decade, which is more than ten times longer than any observed episode of a stars death by black hole. Researchers made this discovery using data from NASA's Chandra X-ray Observatory …

Astronomers find stray black hole hiding in Milky Way
Examining a molecular cloud with enigmatic motion, a team led by researchers in Japan has found signs of stray black hole hiding in the Milky Way. It is difficult to find black holes, because they are completely black. In some cases black holes cause effects which can be seen. Theoretical studies have predicted that 100 …

Black hole spews out cosmic ‘spitballs’
A supermassive black hole in the centre of the Milky Way galaxy flings out planet-sized 'spitballs' formed from fragments of stars shredded by it, scientists have found. Every few thousand years, an unlucky star wanders too close to the black hole whose powerful gravity rips the star apart, sending a long streamer of gas whipping …

Powerful ‘cosmic double whammy’ discovered
Astronomers, using data from India's Giant Metrewave Radio Telescope (GMRT), have discovered two of the most powerful phenomena in the universe – a supermassive black hole and the collision of giant galaxy clusters about two billion light years from Earth. The two phenomenon have combined to create a stupendous cosmic particle accelerator, researchers said. By …
