God's Own Christmas Ornament
In what is one of the best images ever taken by the Cassini spacecraft, Titan and Dione hang in front of Saturn's rings. Like Earth, Saturn has seasons caused by the tilt in its axis. It's presently spring, in Saturn's northern hemisphere. The sun is behind and above the viewpoint, and the shadows of the rings are cast across the southern hemisphere.
The image is in true colour, by the way, so it is exactly what you would see if you were floating in the observation cupola of a clipper outward bound from Rhea en route to Jupiter.
