Rainbow Saturn Cassini's Visual and Infrared Mapping Spectrometer   1 2 3 4 5 6     Silhouetted Clouds This false-color mosaic of Saturn shows deep-level clouds silhouetted against Saturn's glowing interior. This mosaic shows the entire planet, including features like Saturn's ring shadows and the terminator, the boundary between day and night. The blue-green color (lower right) is sunlight scattered off clouds high in Saturn's atmosphere and the red color (upper left) is the glow of thermal radiation from Saturn's warm interior.     Jet Propulsion Laboratory    California Institute of Technology
