Four Ways to See Saturn
NASA's image library records Four Ways to See Saturn.
A montage of Cassini images, taken in four different regions of the spectrum from ultraviolet to near-infrared, demonstrates that there is more to Saturn than meets the eye. The pictures show the effects of absorption and scattering of light at different wavelengths by both atmospheric gas and clouds of differing heights and thicknesses. They also

A montage of Cassini images, taken in four different regions of the spectrum from ultraviolet to near-infrared, demonstrates that there is more to Saturn than meets the eye. The pictures show the effects of absorption and scattering of light at different wavelengths by both atmospheric gas and clouds of differing heights and thicknesses. They also show absorption of light by colored particles mixed with white ammonia clouds in the planet's atmosphere. Contrast has been enhanced to aid visibility of the atmosphere. Cassini's narrow-angle camera took these four images over a period of 20 minutes on April 3, 2004, when the spacecraft was 44.5 million kilometers (27.7 million miles) from the planet. The image scale is approximately 267 kilometers (166 miles) per pixel. All four images show the
