Name: 

 Veil Nebula - NGC 6992 - Distance 1,470 Light Years - In the Constellation Cygnus. .

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.  It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.
