Click for larger image.

The Owl Nebula is a “planetary” nebula about 2,000 light years away and about 8,000 years old. Despite it’s name, the nebula has nothing to do with planets but due to its circular nature early astronomers thought it was a gas planet.

The central star of the nebula is shedding its outer layers of hydrogen (red) and oxygen (green) and the solar winds light it up for us to see.
