![]() ![]() The image was made from data taken by Cassini's composite infrared spectrometer instrument. This image represents the most detailed look to date at the temperature of Saturn's rings. The varying temperatures of Saturn's rings are depicted here in this false-color image from the Cassini spacecraft. Go to NASA photo page - Enhanced Images of Saturn Voyager 2 was 43 million kilometers (27 million miles) from Saturn when it took this photograph. Several changes were apparent in Saturn's atmosphere since Voyager 1's November 1980 encounter, and the planet's rings had brightened considerably due to the higher sun angle. This enhanced-color image was created by combining three images taken through ultraviolet, violet and green filters on July 12, 1981. Go to NASA photo page - Seasons on Saturn These Hubble Space Telescope images, captured from 1996 to 2000, show Saturn's rings open up from just past edge-on to nearly fully open as it moves from autumn towards winter in its Northern Hemisphere. Looming like a giant flying saucer in our outer solar system, Saturn puts on a show as the planet and its magnificent ring system nod majestically over the course of its 29-year journey around the Sun. Go to NASA photo page - Voyager Images of Saturn By contrast, Saturn's rings and icy satellites appear to be composed primarily of water ice. ![]() Above those clouds, Saturn's atmosphere, like those of the Sun and the other three gas giant planets, is composed almost exclusively of hydrogen and helium. Most of the visible markings are formed in a layer of ammonia ice clouds, which form at a pressure level in Saturn's atmosphere that is comparable to sea-level atmospheric pressure on Earth. This 1981 Voyager 2 image shows the vast Saturn ring system, as well as three small icy satellites and the shadow of a fourth. This results in sunlight being scattered at shorter (bluer) wavelengths, thus giving the northernmost latitudes their bluish appearance at visible wavelengths. Saturn's northern hemisphere is presently relatively cloud-free, and rays of sunlight take a long path through the atmosphere. The long, dark lines on the atmosphere are shadows cast by the planet's rings. Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true color view.
