The Western Veil nebula (catalogued as Caldwell 34 and also less formally known as Witch's Broom Nebula) is part of the Cygnus Loop supernova remnant. As the debris from the explosion move at very high speeds through space, they heat the surrounding gas to millions of degrees. As it cools, this creates the colorful glows pictured here. The bright star in the middle of this frame is 52 Cygni, superimposed on the nebula but physically unrelated to the supernova remnant.
