On the left is a geyser shooting a jet of vapor into space. Icy geysers may be responsible for sustaining the E ring's supply of micrometer-sized particles. NASA Artist's rendering of the surface of Rhea, Saturn's second-largest moon.
Titan is the largest.
NASA Artist's rendering of the Huygens probe landing on Titan, Saturn's largest moon. The probe's instruments will directly sample the atmosphere of Titan. The false-color image shows the planets reflected infrared light. This view provides detailed information on the clouds and hazes in Saturn's atmosphere. The image also captured two of Saturn's satellites, Dione on the lower left and Tethys on the upper right.
