The recent opening of the American astronomers a unique opportunity to examine the General theory of relativity in the greatest scale. Scientists have found a star that is at high speed revolves around a supermassive black hole at the heart of our galaxy.

Black hole Sagittarius A*, located in the center of the milky Way, only 10 times larger than the Sun. While its weight in four million times more. Over the past two decades have been discovered thousands of stars that rotate around that object in orbits of different diameter.

A group of astronomers under the leadership Andrea GEZ (Andrea Ghez) from the University of California in Los Angeles with tools Keck Observatory (WM Keck Observatory in Hawaii opened a small star - S0-102, which makes a complete revolution around the black hole in just 11 years from earth speed 10600 kilometers per second. Before closest to the center of the galaxy object was considered another star S0-2 turns 16 years.

"I am very glad that we managed to find another star, who turns around Sagittarius A* faster than take a human life. Because most of the stars in this area have orbit in 60 years and more, " says GEZ, which oversees the S0-2 in 1995. - A kind of tango two stars will help us for the first time to reveal the true geometry of space and time near a black hole. This measurement could be done with only one star".

Einstein's theory says that the body of any mass leads to the distortion (deformation) of space and time, as was proven in normal conditions. But huge black holes often break the traditional view of physicists. GEZ and her colleagues are going to follow what is happening with the orbits of stars near the object possessing enormous gravity.

If Einstein's theory is correct, the orbits of stars will be slightly displaced, and their constellations will never return to the same place. That is why the discovery of two stars with relatively small orbits is a great luck.

According to calculations in 2018 S0-2 will be close to the black hole at the minimum distance, and three years later the same thing will make S0-102. But researchers believe that the effect will be so small that they will probably not be able immediately to notice him, and for review of the relativity Theory will take many years.

The study is published in the journal Science.
