A group of astronomers recorded for the first time the moment of transformation of a star into a black hole. The results of the observation were presented at the 233rd meeting of the American Astronomical Community
this is TheBabel with reference to NASA .
It is estimated that the process took place 200 million years ago. but the light signal has reached our planet only now. The phenomenon resembles the explosion of the supernova – the brightness of the star increases and produces a large amount of energy.
In the scientific community, this phenomenon was called "cow", officially – AT2018cow. It is unusual in this process that, despite the high brightness of the explosion, the release of energy is minimal. The process was observed simultaneously across 18 telescopes – it became a record. Several teams of astrophysicists conducted simulations on the basis of observations and suggested that this process was the birth of a black hole.
