Cassini images reveal the existence of a faint arc of material orbiting with Saturn's small moon Anthe. The moon is moving in a counterclockwise direction in this perspective, and is about to reac...
Anthe's Faint Arc
Faint, ghostly spokes dapple the dark side of Saturn's A ring as the planet's shadow makes a sharp diagonal cut across this image from the Cassini spacecraft. The image was taken in visible light ...
The solar system's largest moon, Ganymede, is captured here alongside the planet Jupiter in a color picture taken by NASA's Cassini spacecraft on Dec. 3, 2000. Ganymede is larger than the pl...
This Cassini image of the Saturn-facing side of icy Mimas reveals the craters and long, linear chasms that cross the moon's surface. Many of the large craters on Mimas have whimsical names from th...

This picture of Eros, the first of an asteroid taken from an orbiting spacecraft, is a mosaic of four images obtained by NEAR on February 14, 2000, immediately after the spacecraft's insertion into...
NEAR's First Whole-Eros Mosaic from Orbit
This radar image of Titan shows a semi-circular feature that may be part of an impact crater. Very few impact craters have been seen on Titan so far, implying that the surface is young. Each new cr...

This diagram shows the trajectory of Cassini's closest Enceladus flybys from the Prime and Equinox missions, relative to the south polar plume, which is shown in false color based on an image taken...
Cassini's Closest Enceladus Fly-bys from the Prime and Equinox Missions
The northern hemisphere of Enceladus is seen in this polar stereographic map, mosaicked from the best-available Cassini and Voyager clear-filter images. The map is centered on the north pole and s...

This wide angle field-of-view artist's rendering shows the surface of Pandora, one of the shepherds of the F ring, a thin wispy band of material just on the outside of the main rings of Saturn. The...
From its station nearly 1.2 billion kilometers (746 million miles) from Earth, the stalwart Cassini spacecraft sends holiday greetings to Earth with this lovely color portrait of Saturn and two of ...
Cassini's Holiday Greetings
This map of Titan's surface brightness was assembled from images taken by the Cassini spacecraft over the past year, both as it approached the Saturn system and during three closer flybys in July, ...
Large and medium-sized impact basins on Rhea's trailing hemisphere are thrown into sharp relief by the grazing rays of the Sun. Bright, wispy features reach across the surface from the east. This ...
