Veil Nebula

Glowing remains of a supernova in Cygnus.

The Veil Nebula is the brightest visible part of the Cygnus Loop, a supernova remnant in Cygnus. The star that exploded was about 20 times the Sun's mass and blew up 10,000 to 20,000 years ago.

The remnant now spans about 3 degrees of sky, six times the full Moon's width. A 2018 measurement puts it about 2,400 light-years away.
