The Bubble Nebula
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.
Messier 52 or M52, also known as NGC 7654, is an open cluster of stars - seen lower left in the full field image. It was discovered by Charles Messier in 1774. It can be seen from Earth under a good night sky with binoculars.
