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 BD+602522, it pushes surrounding sparse gas into a shell.
The energetic starlight then ionizes the shell, causing it to glow. The
Bubble Nebula is about 10 light-years across and visible with a small
telescope towards the constellation of Cassiopeia.
