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."

The Hubble Space Telescope captured images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen.

M27 - Dumbbel Nebula

The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. The Dumbbell Nebula, the beautifully symmetric interstellar gas cloud, is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula.

This impressive color composite highlights subtle jet features in the nebula. It was recorded with a robotic telescope sited in Hawaii using narrow band filters sensitive to emission from oxygen atoms (shown in green) and hydrogen atoms. The hydrogen emission is seen as red (H-alpha) and fainter bluish hues (H-beta).
