The Eastern Veil Nebula
The Eastern Veil Nebula
The Veil nebula is a faint target in the Cygnus Loop, comprised of a super powerful supernova that exploded about 15,000 years ago. This target is determined to be about 2400 light years away. This bright portion is called the Eastern Veil or Caldwell 33 and originally discovered in 1784 by William Herschel. These bubbles are considered to be shockwaves from the supernova and moving as near as 1.5 million kilometers per hour.
