Assembled in the Hubble Palette color map and then modified using the method of Bob Franke's technique - although with some twists of my own.

NGC 7635 is located about 11,300 light years distant and spans 10 light years. The central star is 20 solar masses and excites the nebula with intense radiation.

The Bubble Nebula, is being pushed out by the stellar wind of massive central star BD+602522. Next door, though, lives a giant molecular cloud, visible above the bubble. At this place in space, an irresistible force meets an immovable object in an interesting way. The cloud is able to contain the expansion of the bubble gas, but gets blasted by the hot radiation from the bubble's central star. The radiation heats up dense regions of the molecular cloud causing it to glow. (APOD)
