Composite X-ray (light blue) and optical image of rings around a black hole in V404 Cygni, a binary system in the constellation Cygnus. In 2015, X-ray flares were detected from the black hole producing high energy rings known as light echoes. The light echoes were created when light reflected off dust clouds between V404 Cygni and Earth, forming the concentric rings. | |
