Veil Nebula West
The Veil Nebula (NGC6960) is part of a supernova remnant known as the Cygnus Loop. It is the shattered remains of one, and possibly two, supernovae that exploded down below the bottom of the image more than 15,000 years ago, at a distance of 2,500 light-years from Earth in the direction of the constellation of Cygnus, the Swan. At the time of the explosion, it would have been seen as a very bright star, rivaling the crescent Moon. The bright star near the top centre of the image, known as 52 Cygnus, is not associated with the supernova.
