Scientists have discovered an amazing feature of a black hole. They observed a unique cosmic phenomenon. The radiation of the accretion disk around the black hole was absorbed by the black hole itself. Part of the light bent, and under the influence of the monstrous gravity of a black hole returned to the disk. Then the light from the disk began to reflect. NASA's completed Rossi X-ray Timing Explorer mission helped identify the glow that came directly from the disc.
The reflected light was also captured. Bluish material emanated from the depths of the black hole. It was a stream of energy particles. The black hole has a very large gravitational force, and nothing can escape from its capture, even particles of light. Close to the black hole, this fact is undeniable. But a little further this light may disappear.
Astronomers have determined the reason: black holes are actively growing and emit powerful x-rays. This assumption proves that not all the light that a disk surrounding a black hole emits can be scattered. It lends itself to the power of gravitational waves of a black hole and turns in the opposite direction.
Riley Connors, an expert at the California Institute of Technology, says astronomers have been able to observe the glow very close to a black hole. The light rushed forward, but instead, turned in the opposite direction and was pulled back into the black hole.
Astrophysicists predicted such a situation as far back as the 70s of the last century, but only now it was possible to obtain its evidence. New observations were combined with archival data from the NASA mission that ended in 2012.
The black hole XTE J1550-564, which is powered by the energy of the Sun, pulling the material onto a flat structure around it, called the accretion disk, was studied. Studying X-rays, scientists found fingerprints indicating that the light was deflected back to the disk and reflected.
The disk illuminates itself, and in theory, it was previously assumed that part of the light would deviate from the disk into a black hole, now this is confirmed by real observations.
