This artist's conception simulates an infrared view of the nearly invisible, giant ring around Saturn -- the largest of the giant planet's many rings. It was discovered by NASA's Spitzer Space Telescope. Saturn appears as just a small dot from outside the band of ice and dust. The inset shows an enlarged image of Saturn, as seen by the W.M. Keck Observatory at Mauna Kea, Hawaii, in infrared light.
