The black hole in one of galaxies in constellation of the Sculptor which earlier actively [ad name=”Google Adsense-3 11″] absorbed interstellar gas, stopped now activity and fell into a sleep. This sleep is lasting about ten years. The information obtained by astronomers with help of a NuSTAR telescope from Chandra xray Observatory. The “fallen asleep” black hole weighing about 5 million masses of the Sun is in the center of an active galaxy of NGC 253. In this star system located in 8 million light years from Earth, processes of formation of new stars go with very high speed. The last observations from Chandra xray observatory showed that the black hole actively absorbs gas. According to the astronomers the results testify that the black hole fell asleep over the last ten years. Periodic supervision with help of Chandra xray observatory and  NuSTAR the scientists will be able to tell, whether it woke up again. Scientists note that black holes in the centers of galaxies stop absorbing a matter and fall into hibernation only when in their vicinities are settled “food” stocks. The black hole in NGC 253 is unusual because it fell asleep directly during active processes of a star formation, which go round it. A series of supervision with help of a x-ray NuSTAR telescope of high resolution and the Chandra, carried out in September and November, 2012. This supervision allowed scientists to establish that the black hole in a galaxy doesn’t absorb a matter. As expected, the 350-kilogram NuSTAR telescope will work in an orbit at least two years. The telescope works in the range of x-ray radiation of high energy, and it has sensitivity 100 times higher and spatial permission ten times better, than all other x-ray telescopes.
