Astronomers watched how the black hole woke up from long hibernation, and started absorbing remains of the giant planet. Opening in a galaxy of NGC 4845 located in constellation of the Maiden at distance about 47 million light years, was made by the international observatory of gamma beams of Integral, with XMM-Newton and Swift telescopes, which are located onboard the International space station. Making observations over various galaxies by Integral, the astronomers paid attention to a bright luminescence of NGC 4845 in the x-ray range. Then, using XMM-Newton telescope, was confirmed the nature of this luminescence. Earlier it wasn’t observed similar phenomenon. The scientists notes that the opening was absolutely unexpected opening, regarding the galaxy, which had been quiet during last 20-30 years. According to the estimates, the object absorbs a giant planet, because the mass of object can be more than the mass of Jupiter approximately 14-30 times. Though the astronomers note that the real weight can be below, it can correspond to the mass of Earth. The flaring event in NGC 4845 may be seen as warm-up act, which expected in the supermassive black hole at the Milky Way Galaxy center. Along with the object, which being eaten by the black hole, these events will help the astronomers to know more about the happenings of different types objects, because they encounter black holes of varying sizes. According to the astronomers for the first time they observe how the black hole destroys the object not similar by the nature to a star, but with mass like a giant planet. According to this estimation, the black hole ate only external layers of the object, which forced a planet to grow thin for 10% of its weight. Most likely, the dense kernel of object still rotates round a black hole. The astronomers estimate, that such kind of events may be detectable every few years in galaxies, and the Integral will be able to watch them just as it did with NGC 4845.
