Description

NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. The bubble is created by the stellar wind from a massive, hot, 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. It was discovered in 1787 by Friedrich Wilhelm Herschel. Distance from Earth ~11000 light years. This widefield also includes M52 aka NGC 7654, an open cluster of stars in the northern constellation of Cassiopeia, NGC7538 the Northern Lagoon Nebula aka Brain Nebula – Dreyer’s Object and part of the Lobster Claw Nebula (SH2-157).
