NGC 7635 - The Bubble Nebula

NGC 7635 (also known as the Bubble Nebula) in the constellation Cassiopeia is a H II region, emission nebula. 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 young central star, SAO 20575 (BD+60 2522). 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.
