NGC 7635 Bubble Nebula
The Bubble Nebula (NGC7635) is one of three shells of gas surrounding the massive star BD+602522, the bright star near the center of the bubble. Energetic radiation from the star ionizes the shell, causing it to glow. This image was taken with broadband filters. A narrowband image of this object is also available in this gallery.
