NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region [1] emission nebula in the constellation Cassiopeia. It lies close to the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 [1] magnitude young central star, SAO 20575 (BD+60°2522). [7]

NGC 7635（Sh2-162、Caldwell 11）は、カシオペヤ座に位置する散光星雲（HII領域 [1] ）である。この星雲は、M52の近くに位置して見える。この星雲は1787年に、ウィリアム・ハーシェルによって発見された [3] 。

SH2-162 (Bubble Nebula) One of the most common objects to image in the cool months of fall is the Bubble Nebula. This object gives imagers many choices of how to image this nebula using normal RGB filters or narrowband filters.

2021年10月12日 · The LOBSTER CLAW (SH2-157) & BUBBLE NEBULA (SH2-162), or Sharpless 157 (Sh2-157), is an emission nebula, around 12,000 light-years from Earth between the Cassiopeia and Cepheus constellations. There are several interesting features in this nebula rich region, including the Bubble Nebula,

The blue (OIII) Bubble is embedded in a large orange-brown (H-alpha/SII) emission nebula Sh2-162. Notice that the color of that knot next to the Wolf-Rayet star in the Hubble palette image (“HubblePalette.jpg”) is orange-brown like the surrounding Sh2-162, not blue like the Bubble itself.

The Bubble Nebula (NGC 7635, Sharpless 162, or Caldwell 11), is an emission nebula in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a massive central star,SAO 20575 (estimated mass 10-40 Solar masses).

2024年9月2日 · The Bubble Nebula, or Sharpless 162, is an H II region emission nebula in the constellation of Cassiopeia. It lies close to the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, young central star.

SH2-162 (also known as NGC 7635 or Bubble Nebula) is an emission nebula in constellation Cassiopeia. The region is ionized by the hot young O-type star BD +60 2522 which lies at a distance of about 9800 ly (light years) from Earth (Gaia DR3 data).
