Description

Bubble NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an 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 young central star, SAO 20575 Distance to Earth: 11,090 light years. The Bubble Nebula is 7 light-years across.  The Bubble Nebula was created about 300,000 years ago, when the central star expelled a shell of dust and gas. The expelled material rapidly moved away from the star and, as it interacted with the nearby molecular cloud, it began to create the nebula's bubble shape.
