Helix Nebula (NGC 7293) - a photo on Flickriver

            A planetary nebula, the "Helix" was formed starting only about 10,000 years ago from gases shed by a dying star, with the outer layers expanding somewhat faster than the inner layers. The remaining core of the star is so energetic that it excites the expanding the gases, causing them to glow.

The Helix Nebula is often noteworthy for its resemblance to an "eye in the sky" from our vantage from Earth; it's alternately referred to as the "Eye of God" and even "The Eye of Sauron". In reality, though, it is thought to be shaped as a prolate spheroid, somewhat resembling a football.
