An international team of scientists was able to identify signs of event horizons in a black hole. Thus, it becomes possible to unmistakably separate those from neutron stars.

These luminaries are comparable in mass and size to black holes. The latter are devoid of a solid surface, which contradicts the general theory of relativity. However, in this case, black holes must have an invisible boundary called the event horizon. Even the light cannot overcome it. To have a chance to prove the existence of black holes of stellar masses, it remains necessary to be able to distinguish regions of space-time from neutron stars. As part of the new work, its authors analyzed the X-ray data obtained from the Rossi X-Ray Timing Explorer satellite.

The available images made it possible to reveal the absence of a solid surface in the considered X-ray radiation. In addition, astrophysicists have recorded a significant signature of stellar accretion.
