| NGC7635 is a HII region emission nebula in the constellation of Cassiopeia. The bubble is created by the radiation pressure from a young 8.7 magnitude star, SAO 20575 which solar wind blows at 2000km/s. It's a blue giant star also reponsible of the molecular cloud ionization, causing it to glow. Its distance is estimated around 11000 l.y. [Wiki)] |
