The Veil Nebula

Veil Nebula smallThe Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It’s the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova exploded between 5,000 to 8,000 years ago, and the remnants have since expanded to cover a swath of the sky roughly 3 degrees across, about 6 times the diameter of the Full Moon.
