Cygnus Loop, The Veil Nebula

The Veil Nebula, also known as the Cygnus Loop or Cirrus Nebula, is the remnant of a supernova explosion that occurred about 10,000 years ago. It is located 1,400 light years away in the constellation of Cygnus. It is very large at about 3 degrees in diameter.

NGC 6992/95 is the brighter eastern half of the nebula at left.

NGC 6960, The Witch's Broom, is the portion of the supernova remnant that appears close to the bright star 52 Cygnus at lower right.

Pickering's Triangular Wisp, above and to the left of the NGC 6960, is designated as Simeis 3-188. At the top center of the photo is a small patch of the Veil designated as NGC 6974/79.
