These flares are the first direct observation of light from behind a black hole. As you know, this is a cosmic phenomenon
In a new study, a University astrophysicistStanford's Dan Wilkins studied a supermassive black hole at the center of a galaxy 800 million light-years from Earth. During observations of X-ray flares, telescopes recorded additional flares that appeared later than the main ones, they were less bright and of different “colors”. These light echoes, or reflections, were calculated to correspond to X-rays that bounced off the back of the black hole.
Any light that hits the black hole is notcomes out of it, so we must not see what is behind. The reason scientists have observed flares is because the black hole bends space, deflects light, and twirls magnetic fields around it.
Initially, the research was aimed atstudying the corona, an element that some black holes possess. Material falling into a supermassive black hole fuels the brightest continuous light sources in the universe and in the process forms a corona of X-ray light around the black hole.
The authors will continue to describe and study the black crownsholes. They pin special hopes on the Athena space telescope of the European Space Agency. It is noted that its launch is planned in 10 years.
