The mysterious discovery of a black hole in the middle of our galaxy

UCLA scientists say they've recorded a mysterious and unprecedented flash from the black hole in the middle of our galaxy.

Scientists have revealed that the mbad of the huge black hole Sagittarius A *, about 4 million times more than the mbad of the sun, had emitted a flash of radiation in May, which is greater than anything we have never seen.

The sudden brilliance of brightness made the black hole 75 times brighter than normal before returning to normal.

In a statement to ScienceAlert, astronomer Tuan Do of the University of California at Los Angeles said: "At first I was surprised.The black hole was so bright that I originally thought that It was the S0-2 star, since I've never seen Sgr A * shine. "

The phenomenon was captured with the aid of WM Keck observatory in Hawaii and was recorded for four nights. In a video published by scientists, the flash, which lasted more than two hours, was reduced to a few seconds per time interval.

The black hole is constantly changing, but the detected event seemed brighter when it is seen in the infrared.

While black holes flicker regularly and fluctuate slightly from one moment to the next, the large radiation detected by scientists in May suggests that a larger object has been discovered by the gravity of the black hole .

Scientists have explained that the sudden flash is as vague as it is abnormal, but they badume that it can be stimulated by a close approach to a star called S0-2.

The results should be published in a research article that has not yet been published in the journal Astrophysical Journal Letters, which is being printed in ArXiv.
