8 X-ray rings detected around a black hole by NASA; pic released

Astronomers have spotted eight "huge" rings around a black hole in an image captured using Chandra X-ray Observatory and Neil Gehrels Swift Observatory. "The X-ray images of the giant rings have revealed new information about dust located in our Galaxy," NASA said. The black hole is a part of a binary system called V404 Cygni, located about 7,800 light-years away.
