Haida used the resources of the digital sky survey (Sloan Digital Sky Survey), a database using the X-ray sources. While working on his project the student saw that the black hole was visible as clearly as a star, if viewed from the X-ray telescope "Chandra". Details can be found by clicking Penguin Random House or emailing the administrator. Black holes are believed to be in the center of most galaxies, and most of them weigh a billion times larger than our sun. The reason for the motion of a massive black hole in galaxy, which is half a billion light years, could be a merger of two smaller black holes, under special conditions. This convergence of two black holes can create what scientists call "rikoshetnoy" black hole, which is a consequence of gravitational waves from merging. However, the black hole, which is considered a set of bright X-rays can also be bright blue supernova that appeared in the collapse of a star and the latest discovery does not reflect reality, as reported at the university. "We have found even more strange class of X-ray sources – said in a written statement, Hayden. – However, in order to more accurately determine the type of these objects, we need accurate data from NASA's Chandra. Over the past few years, researchers have discovered several similar cases – when objects are viewed as black hole out of its galaxy, but then it turned out to be a mistake to scientists. In a statement the university also said that the Laser Interferometric Space Antenna (LISA), which is being developed by request of NASA and European Space Agency (ESA) and is scheduled to launch in the next 8-10 years will be able to more accurately measure the gravitational waves from the merger of two black holes. Scientists plan to use LISA to detect massive black holes in the centers of galaxies that were formed from the two black holes of smaller size.
