Astrophysics saw a black hole sculpts the stars from the clouds

An international team of researchers led by Michael McDonald of the Massachusetts Institute of technology have discovered that supermassive black hole in the galaxy Abell 2597 absorbs the cool gas around them and increases in size. The energy released at the same time, contributes to the running of the process of formation of new stars, experts suggest.

Galaxy Abell 2597 is located in the constellation of Aquarius at a distance of about a billion light years from Earth. Watch as a black hole in its center, draws in a huge cloud of cold gas, scientists were able for the first time. The speed of motion of the gas, according to the experts data, reaches up to 355 kilometers per second, or 1.2 million kilometers per hour. Weight seeking into the black hole gas clouds by calculations of experts, at millions of times the mass of planet Earth.

Until now it was assumed that black holes “eat” only the hot gas that surrounds them constantly, and they suck these gases is quite slow. From a mathematical point of view, such a model, according to the scientists, looked much easier, though did not give a definite answer to the question, how did black holes truly colossal proportions.. However, new evidence suggests that inside spheres of hot gas are clouds of cold gas, which also sometimes serves as “food” for the black hole, and if the gas feeds her constantly, but slowly, the cold rare, but large portions — so large, that “surplus” energy the black hole emits in the form of jets flying at near-light speed narrow beam of hot plasma. This, according to Michael MacDonald, suggests that the growth of black holes is a much more chaotic process than previously thought.

The scientists published their study in the journal Nature. They hope that their study will help better understand the nature of the growth of black holes and, probably, will allow to a greater extent to understand the structure and history of galaxies in General.
