The Veil Nebula (NGC 6960) is part of a supernova remnant known as the Cygnus Loop. It is the shattered remains of one, and possibly two, supernovae that exploded 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 centre of the image, 52 Cygnus, is not associated with the supernova.
