The Cygnus Loop is a supernova remnant located in the constellation Cygnus, approximately 1,500 light-years away from Earth. It is one of the largest and brightest supernova remnants in the sky, covering an area of approximately 3 degrees in diameter (which is about six times the size of the full moon). The Cygnus Loop is the remnant of a massive star that exploded at the end of its life, releasing a massive amount of energy and ejecting material into space.
