The Veil Nebula, also known as the Cygnus Loop, is a supernova remnant in the constellation Cygnus. It is composed of wispy, filamentary structures of ionized gas, primarily hydrogen and oxygen, which glow in shades of red and blue. The nebula is illuminated by the shock waves from a supernova explosion that occurred approximately 8,000 years ago.
