It is no secret that black holes — the most mysterious objects in the Universe. But what are they? Speaking in plain language, black holes are objects with extreme density. Because of their weight, they have a strong gravitational pull. It is so strong that even light gets trapped when passing by a black hole. Once inside, he could get out he can not. Questions about the nature of black holes — the mass. And recently they became even more — according to scientists, the black hole at the center of the milky Way lately is behaving oddly.
The Milky Way Galaxy
The black hole in the center of the milky Way is in the constellation of Sagittarius A. this region see a variety of telescopes, including Spitzer and Chandra. Studying matter close to a black hole in may of this year, scientists noticed that it is more active than usual — its event horizon becomes brighter. Scientists say that a black hole in the constellation Sagittarius And is a pretty quiet unit but according to new data the situation has changed.
May 13, astronomers saw a relatively low reduced brightness, suggesting that the black hole was unknown peak, which was even brighter. According to information received, the recent outbreak has led to the fact that the event horizon of a black hole is brighter in two times. Note that a similar phenomenon scientists are watching for the first time.
Russian telescope ART-XC
According to the researchers, the unusual behavior of a black hole could be caused by a close passage of a star called S0-2 in 2018 or object called G2 in 2014. Monitor changed brightness of the event horizon of a black hole in the constellation Sagittarius And will be continued. To study the black hole at the center of our galaxy, recently joined the ART-XC — a new Russian space telescope, launched about a month ago.
