Description

The Cirrus Nebula is the western portion of the much larger complex known as the Veil Nebula, seen in a wider view here. It is part of a bubble of expanding gas and dust whose source was a supernova star that exploded in the distant past. The nebula is also sometimes called the "Witch's Broom". The bright star near the center of the nebula is 52 Cygni which actually lies much closer to us at a distance of 204 light years than the nebula itself at a distance of 1400 light years.
