Description

NGC 7635 (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. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude 10-40 solar mass 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.

M52 (Salt & Pepper Open Cluster)

Messier 52 (also known as M 52 or NGC 7654) is an open cluster in the Cassiopeia constellation.
