Pickering's Triangle (NGC 6979)

Pickering's Triangle (NGC 6979) Chaotically arranged filaments of gas, glowing under the influence of shock waves, fill this region of planet Earth's sky in the constellation Cygnus. They are part of the Veil Nebula. The Veil Nebula is a large supernova remnant—an expanding cloud formed after the explosion of a massive star. The light from the supernova explosion likely reached Earth more than 5,000 years ago. The explosion created interstellar shock waves that sweep through the surrounding space, gathering and energizing interstellar material.
