Photograph Description

The Bubble Nebula is actually the smallest of three bubbles surrounding massive star BD+602522, and part of gigantic bubble network S162 created with the help of other massive stars. As fast moving gas expands off of the central star, it pushes surrounding sparse gas into a shell. The energetic starlight then ionizes the shell, causing it to glow.
