Scientists who run the Keck Observatory (two observatories at 4145 meters altitude at the top of Mauna Kea in Hawaii) recorded a powerful explosion near the gigantic black hole "Sgr A *" located in the center of the galaxy of the Milky Way.
The explosion, which occurred late May, could destroy a star or absorb a large amount of material, said astronomer Phil Plate.
"We now have two hypotheses," said astronomer Tuan Do, of the University of California at Los Angeles, USA. "The first is that the black hole" Sgr A * "could absorb the star" S0-2 "that approached it in May of last year.The second assumption does not exclude the possibility that the black hole reaches a part of the gas cloud G2, which approached it from a dangerous distance five years ago.
It is called "living" an abnormal black hole in the center of the Milky Way and all other galaxies in the universe. The hole in our galaxy is four million times heavier than the Sun and 26,000 light years from Earth.
Surrounded by dozens of stars and many gas clouds, this black hole, which scientists call "Sgr A *", periodically approaches a dangerous distance from the hole.
Here is a timelapse of images of more than 2.5 hours from May from @keckobservatory the supermassive black hole Sgr A *. The black hole is still variable, but it was the brightest we have seen in the infrared until now. It was probably even brighter before we started watching tonight! pic.twitter.com/MwXioZ7twV

Interestingly, the black hole "Sgr A *", unlike many huge black holes, is dormant and shows no case of activity. It was supposed to be woken up after absorbing a star or a cloud of gas, thus giving scientists a chance to study it in more detail in terms of the emissions and the way it absorbed the material.
Astronomers would never have been able to materialize these hopes, as the observations showed that the first approach of the black hole with the star and the gas cloud did not end at all, as the black hole did not end at all; absorbed no part of the material and that no explosion was recorded.
According to scientist Phil Plate, the situation has changed dramatically in mid-May this year, when the world and his colleagues began to record dramatic and very rapid changes in the power of the infrared glow of the black hole, where its glow , sometimes more than 75 times that of Normal, then dropped very quickly.
According to the world, most of the heat and light of the black hole is absorbed by a thick "layer" of dust and gas that surrounds the center of the galaxy. These abrupt changes and changes in the behavior of the hole can therefore be a sign of its awakening.
