NASA's Chandra Space X-ray Observatory has recorded luminous rings around a black hole in the V404 Cygni binary system, located 7,800 light-years from Earth.

The observatory snapped a picture of the black hole in conjunction with the Neil Gehrels Swift Observatory, which is jointly run by the United States, Italy, and the United Kingdom. Scientists managed to detect the rings precisely by capturing X-rays.

Astronomers First Spot Light Behind a Supermassive Black Hole
This discovery confirms the general theory of relativity, according to which the gravitational attraction of black holes warps space, bends light rays, and twists magnetic fields around itself, allowing you to see the light echo.

The V404 Cygni system is a binary one, consisting of the star itself (whose mass is about half the mass of the Sun) and a black hole (the mass of which is about twelve times that of the Sun).

X-rays from the system were reflected from the clouds of cosmic dust located between the binary system and the Earth, and created the effect of glowing circles, which can be seen in the image. The observatory recorded the radiation in July-August 2015.

Studying the rings formed in the image will allow scientists to learn more about the space between V404 Cygni and Earth and the black hole in the system.
