Wow....

 A fascinating astronomy image today! Behold:


NASA explains:

A spectacular set of rings around a black hole has been captured using NASA's 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, using a similar principle to the X-rays performed in doctor's offices and airports. 
The black hole is part of a binary system called V404 Cygni, located about 7,800 light-years away from Earth. The black hole is actively pulling material away from a companion star — with about half the mass of the Sun — into a disk around the invisible object. This material glows in X-rays, so astronomers refer to these systems as "X-ray binaries. 
 ... 
In a new composite image, X-rays from Chandra (light blue) have been combined with optical data from the Pan-STARRS telescope on Hawaii that show the stars in the field of view.

Amazing!
