This is a picture of a Bubble Nebula, NGC 7635, being pushed by the stellar wind of the massive central star BD+602522. The Nebula is able to contain the expansion of bubble gas, but when the hot radiation from the bubble's central star it heats up dense regions of the molecular cloud. This causes it to glow. The Bubble Nebula is 10 light years across and can be seen with a small telescope.
