Astronomers have found that Sagittarius A *, supermassive Black hole a mysterious flash formed in the center of the Milky Way. Its brightness has increased 75 times, which is why scientists do not know, reports Popular Mechanics.
It should be noted that Sagittarius A * behaves relatively calmly. At the same time, observations of the black hole, which were carried out with the help of the Keck Observatory in May, showed that its brightness in the near-infrared range increased significantly, and then returned to the previous level.
As a rule, if the black hole's environment increases brightness, it may mean that something has come close enough to the hole and has been caught by its gravity. What would be the case with the recent sudden outbreak of Sagittarius A * is not clear.
One possible explanation is for the G2 object, which in 2014 approached a black hole 36 light years away. Scientists assumed that it was a cloud of gas, but if so, it should have been torn to shreds, which did not happen. Perhaps the recorded outbreak was a belated response to this event.
Another explanation is related to the star S0-2, which is in an elliptical orbit around the black hole and approached it last year for 17 light years. According to the researchers, due to the near transition of S0-2 near Sagittarius A *, the way the gas enters the black hole may change; this could lead to increased gas flow and increased variability of Sagittarius A *.

Astronomers have previously discovered an ultra-massive black hole that is at the center of the Holmberg 15A galaxy 700 million light-years away from Earth. The mass of the black hole is estimated at 40 billion Suns, which makes it record holder among similar objects.
