The Veil Nebula, also the Nebula Nebula or Nebula The fishing net is a diffuse nebula in the constellation Cygnus, a huge and relatively dim supernova remnant. The star exploded about 5000-8000 years ago, and during this time the nebula covered in the sky an area of 3 degrees or about 6 times the diameter of the full Moon. The distance to it is estimated at 1470 light years. This nebula was discovered on September 5, 1784 by William Herschel. The nebula is so large that its parts are considered separate nebulae and have their own names, such as the Witch’s Broom Nebula (NGC 6960 or LBN 191), Pickering Triangle (NGC 6979), Pike (NGC 6992), NGC 6995 together with NGC 6992 forms the Nebula Nebula, NGC 6974 and NGC 6979.
The red color is hydrogen, blue-green oxygen.
