This is only a small portion of the much larger Veil Nebula, located in the eastern half. It is shown in absolutely stunning detail when viewed in a large telescope with a UHC or Olll filter.This Supernova remnant in particular actually exploded over 15,000 years ago, shown here is the expanding debris from this former star. This section is also know as the Cygnus Loop. It is located over 1,400 light years away.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It is a large but relatively faint supernova remnant.The green colored gases in the image are believed to be sulpher. The red colored gases appear to be hydrogen. And any other gases presence must be oxygen. Also, the bright blue star, dubbed 52 Cygni, is unrelated to the supernova explosion, can be observed with the naked eye on a clear summer night.
