The Veil Nebula
is a supernova remnant in the constellation Cygnus.
Also known as the Cygnus Loop and the Witch's Broom Nebula.
Discovered by William Herschel in 1784, this nebula spans an
area of sky equal to about six times the diameter of the
Moon. The supernova that produced this gas cloud
exploded between 5000 and 8000 years ago. Its distance is
not accurately known, but is estimated to be between 1400
and 2600 light years away. |
