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. 1http://antwrp.gsfc.nasa.gov/apod/ap000118.html
