From
wikipedia:
The
Veil Nebula, is part of the
Cygnus Loop, radio source W78, or Sharpless 103. Other parts of the loop include the 'Eastern Veil', the 'Western Veil' or 'Witch's Broom Nebula', and Pickering's Triangular Wisp. It is a large, relatively faint
supernova remnant in the constellation
Cygnus. The source
supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area of ~3x3 degrees; about 6 times the diameter or 36 times the area of a full moon. The distance to the nebula is not precisely known, with estimates ranging from 1,400 to 2,600
light-years. It was discovered on 1784 September 5 by
William Herschel. He described the western end of the nebula as
"Extended; passes thro' 52 Cygni... near 2 degree in length." and described the eastern end as
"Branching nebulosity... The following part divides into several streams uniting again towards the south."
