The Veil Nebula—A Supernova Remnant The Cygnus Loop is a roughly spherical remnant of a supernova that exploded about 8,000 years ago. The distance to the nebula is about 1,500 ly and the overall diameter of the loop is about 100,000 ly. This supernova remnant is so large that it covers an area of about 45 full moons! The image contains more than 1.6 Gb of data and is one of the largest astronomical images ever made.
