The Cygnus Loop is a huge supernova remnant some 2,500 light-years away. It has many components, and this image shows two of them well. At the top is the Witch’s Broom (NGC 6960), and Pickering’s Triangle (which doesn’t have its own designation) lies down and to the lower left of the Broom. Naresh Singh from Saint Petersburg, Florida
