NGC7635 - The Bubble Nebula
Image Information
Quoted From APOD
Explanation: What created this huge space bubble? A
massive star
that is not only bright and blue, but also emitting a fast
stellar wind of
ionized gas. 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, also known as NGC 7635, is about 10 light-years
across and visible with a small telescope towards the constellation
of
Cassiopeia.
