The Cassini spacecraft has been documenting Saturn and its moons for the past five years. Above is an image of Saturn's largest moon, Titan, revealing its halo-like ring formed in the upper hazes of the moon's extensive atmosphere. This image reminded me of my astronomy plates.
If you have not yet visited NASA's website devoted to Cassini's mission, do so now. It is a visual, and an educational, treat.
