NGC 7635- The Bubble Nebula. Like many things of nature, the most innocent of appearances is linked to the most violent. The bubble itself has a diameter of 10 light years, with an O star in the center. The O star alone is over 100,000 times for luminous and 45 times bigger than our Sun. The Bubble Nebula is a result of violent winds from a massive star. The wind combined with the radiation blasted the Bubble Nebula into its shape. The Bubble is surrounded by a dense molecular cloud containing ionized hydrogen and oxygen. From Earth, the Bubble Nebula is 11,000 light years away- just little bigger than the bubble itself.
