Crescent Rhea Occults Saturn
- The slim crescent of the moon Rhea glides silently onto the featureless, golden face of Saturn in this mesmerizing color movie. In an interplay of contrast and shadow, the moon goes dark against the planet, and then its crescent suddenly brightens as it slips in front of Saturn's night side.
This view looks down onto the unlit side of Saturn's rings, which cast soft, linear shadows onto the planet's northern hemisphere.
This still image is one frame from 60 images taken using red, green and blue spectral filters over a period of about 45 minute showing an animation of the Reah
sliding across the face of Saturn.
