42 million light-years away, 20 million times the mass of the Sun, and coming back to life. A team of radio astronomers, led by Megan Argo of the Jodrell Bank Center for Astrophysics, is watching a previously dormant black hole wake up in a dramatic The discovery runs counter to most observations about black holes, which are massive areas of space with extraordinarily strong gravity that can pull in anything -- even light. In most cases, black holes and their host galaxies expand at the same rate. Astronomers investigated a supermassive black hole known as CID-947, located about 22 billion light-years from Earth, using the W.M. Keck Observatory in Hawaii, NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton spacecraft. The NuStar observatory is usually used to find black holes far from our Solar System, but astronomers have now utilized the tool to examine our own sun. These observations reveal the pattern of X-rays emitted by our local star. The Nuclear Spectroscopic A NASA satellite detected the first sign of a black hole 8,000 light years away from Earth on Jun 15, 2015. Astronomers around the world are studying the event. Before you start thinking that aliens must exist and be quite passionate about playing darts, you should know that the image shows not a cosmic shooting target but rings of X-ray light neatly arranged around an erupting black hole. “What looks like a .
The data, collected with a new instrument, revealed a giant black hole in an otherwise normal, distant galaxy, called CID-947. Because its light had to travel a very long distance, the scientists were observing it at a period when the universe was less (Nanowerk News) What looks like a shooting target is actually an image of nested rings of X-ray light centered on an erupting black hole. On June 15, NASA's Swift satellite detected the start of a new outburst from V404 Cygni, where a black hole and a sun In the case of BL Lac, the ions are in the form of particle jets that are flung from opposite sides of the black hole at near light speed. "Imagine running a water hose through a slinky that has been stretched taut," said first author Marshall Cohen The black hole at the center of a galaxy 42 million light years away, in the constellation of Pisces, may have been dormant for millions of years, a team reported Thursday. Scientists surveying the skies were lucky in 2012 to catch a flash of its awakening .
