Last couple of days, I was able to image this amazing stellar structure from my backyard in North Carolina. Inspired by the famous Hubble Space telescope and so many amazing images @Astrobin, 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. 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. (Desc creditc: Wikipedia) The NGC7635 nebula is an amazing and very curious structure, with beautiful lightness that simulates a soap bubble. According to NASA the star at upper half star, it is a bright O-type star that produced the stellar winds that ultimately shaped the nebula. The bubble is approximately seven light-years wide.
