The Veil Nebula

The Veil nebula consists of different parts, each with their own designation. The best known ones are NGC6960, or the Eastern Veil Nebula, and NGC6992/NGC6995, or the Western Veil Nebula.

 

"The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon)."
