. Astrophysics for the first time fully saw, like a black hole tearing apart star, «chews» her remains and «spits» them in space. Photos and findings of scientists published in the journal Science.

«We’ve never been able to see how is this release. Most of the time, supermassive black holes no break off and remain virtually invisible to us. In fact, we have a unique chance to understand what happens near the black hole during these «gaps,» said Miguel Perez-Torres (Miguel Perez-Torres), an astrophysicist at the Astrophysical Institute of Andalusia in Granada (Spain).

It is believed that in the center of the most massive galaxies, there is at least one supermassive black hole. The reasons for the formation of these objects is still not entirely clear. Observing the curvature of space around them suggests that the typical mass of supermassive black holes is in the range of one million to several billion solar masses.

Perez-Torres and his colleagues for several decades to see how the supermassive black holes in distant galaxies tear apart and eat them near to the stars, trying to understand their dying light «Crick» that surrounds such black holes and how they destroy the star.

Up to the present time, as the scientist, his team failed to catch black holes in the first phases of their «meal» when they have already begun to destroy the star, but haven’t started to eat her remains and throw the «leftovers» in the form of jets, narrow beams of plasma accelerated to near-light speeds.

In January 2005, after many years of searching, scientists were lucky – infrared telescope WHT observing the night sky of the Northern hemisphere in the Hawaiian Islands, recorded the flash of heat in the core of the galaxy Arp 299, located in the constellation URSA major at a distance of 150 million light years from Earth.

This galaxy, as they note, emerged in the recent past as a result of collision of two standalone «star cities», IC 694 and NGC 3690. Their merger has led to the fact that all the gas in one and in another galaxy were «scrambled,» which led to the birth of thousands of new stars and the destabilization of the orbits of old stars.

Some of the newborn and old stars, as told by Perez-Torres, was dangerously close to a supermassive black hole with a mass of 20 million Suns, living in the center of Arp 299. One of these stars, whose mass was higher than the sun about 4-6 times, met his fate some 150 million years ago, in the era of the dinosaurs. We’ve seen evidence of this cataclysm only thirteen years ago because of the enormous distances between the Milky Way and Arp 299.

In the summer of 2005 traces of a «lunch» of a black hole was seen by the VLBA radio telescope, and then it was discovered by optical ground-based telescopes and orbiting x-ray Observatory «Spitzer». These observations scientists continued over the next ten years, until all traces of the activity of the black hole has not disappeared from the night sky.

Analysis of photographs and data collected at that time, helped astrophysicists reveal some interesting characteristics of the «diet» large black holes. For example, they found that matter is it «spitting» overclocked up to a quarter of the speed of light, confirmed that it has a narrow, conical shape and a calculated position of the point where the jet is born.

In total, during the «meal» black hole produced more light and other forms of radiation than it produces approximately a million stars similar to the Sun, during his life, or 10 powerful supernova.

These data, as astrophysicists hope will help other scientists to understand what accelerates the jet matter and why some supermassive black holes constantly throws out like beams of plasma, while others, like the hole in Arp 299 or in the center of the milky Way, are relatively quiet.
