Description

NGC 7635, also known as the Bubble Nebula, is an 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, 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.
