Description
A planetary nebula in the constellation Aquarius, approximately 700 light years from earth. Planetary nebulae are the remains of modestly sized stars, similar to our sun, which, having expended their nuclear fuel shed mass and collapse to white dwarfs. The Helix Nebula, because it is relatively close to earth--compared to other planetary nebula--appears very large, approximately one half the diameter of the full moon.
