Description

NGC 7635, also known as the Bubble Nebula or Sharpless 162 was discovered in 1787 by William Herschel. At distance of ~7100 ly in constellation Cassiopeia, the bubble is 7 light years in diameter and is formed by very hot and massive O-star - the one at 6 o'clock near the border. The hot stellar winds forming the nebula are facing bigger resistance cold interstellar clouds in the lower part of the image than in the other directions, so the nebula expands uneven. This is the reason the star to be off the bubble center. The nearby cool hydrogen gas is shaped in pillars similar to the famous "Pillars Of Creation" and their presence is a sing of possible star formation activities.
