Saturn's moon Prometheus casts a shadow on the narrow F ring in this image captured weeks after the planet's August 2009 equinox. The gravity of potato-shaped Prometheus (86 kilometers, or 53 mile...

Oozing Across Titan November 8, 2004 Full-Res: PIA06993 This synthetic aperture radar image of the surface of Saturn's moon Titan was acq...

The Cassini spacecraft gazes down at linear tectonic features in Dione's northern hemisphere. These features -- several canyons and at least one ridge -- are also visible in the upper right quadra...

Global images of Earth from Galileo. In each frame, the continent of Antarctica is visible at the bottom of the globe. South America may be seen in the first frame (top left), the great Pacific Oce...

This anaglyph made from images captured by NASA’s Cassini spacecraft shows a dramatic, 3-D view of one of the deep fractures nicknamed "tiger stripes" on Saturn’s moon Enceladus. The fractures, whi...

The Cassini spacecraft watches a thin, bright sliver emerge from the hazy limb of Saturn. In one minute, the sliver ballooned into the full disk of Mimas (397 kilometers, or 247 miles across), whic...

Bright spokes grace Saturn's B ring in this Cassini spacecraft snapshot that also features a couple of the planet's moons large and small. Dione (1,123 kilometers, or 698 miles across) can be seen...

A collection of new ring phenomena, first observed in the sequence of images taken of the dark side of Saturn's rings immediately after Cassini entered orbit, may be evidence of the clumping and ag...

Following a successful close flyby of Enceladus, NASA's Cassini spacecraft captured this artful composition of the icy moon with Saturn's rings beyond.

These raw, unprocessed images of Saturn's moon Dione were taken on Dec. 12, 2011, by NASA's Cassini spacecraft. Although Cassini obtained more detailed images on previous flybys of Dione, this was ...

This image shows three slices of a class of meteorites that fell to Earth that NASA's Dawn mission has confirmed as originating from the giant asteroid Vesta.

A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA's Cassini spacecraft.

This false-color mosaic of Saturn's largest moon Titan, obtained by Cassini's visual and infrared mapping spectrometer, shows what scientists interpret as an icy volcano (see inset). The mosaic was...

The three very different moons seen here provide targets of great interest for planetary scientists studying the Saturn system. Captured here by Cassini, along with the rings, are Tethys at upper r...

The Cassini spacecraft profiles several features oriented north-south on Saturn's moon Tethys. A line of craters runs north to south near the center of the image: (from top) Phemius, Polyphemus, A...

+ View Unannotated Version The dark hot spot in this false-color image from NASA's Cassini spacecraft is a window deep into Jupiter's atmosphere. All around it are layers of higher clouds, with ...

From beneath the ring plane, the small, irregularly shaped moon Janus (181 kilometers, or 112 miles, across) can be seen following the orbital path it shares with slightly smaller Epimetheus (116 k...

This global map of Saturn's moon Tethys was created using images taken during Cassini spacecraft flybys. The map is an equidistant (simple cylindrical) projection and has a scale of 293 meters (96...

Saturn's rings, partially darkened by the planet's shadow, cut a striking figure before Saturn's largest moon, Titan. The night side of the planet is to the left, out of the frame of the image. Il...

+ Viewing options The moon Tethys is joined by two smaller moons in this movie from NASA's Cassini spacecraft. Observations of mutual moon-crossing events, in which one moon passes close to or i...

Saturn's moon Prometheus chases Pandora in this Cassini view, but the outcome of their race has already been decided by gravity. Prometheus orbits closer to Saturn and thus moves faster than does P...

These six infrared images of Saturn's moon Titan were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer instrument on board NASA's Cassini spacecraft.

These three enhanced-color views of an equatorial region on Saturn’s moon Rhea were made from data obtained by NASA’s Cassini spacecraft. The colors have been enhanced to show colorful splotches an...

A broad and ghostly spoke drifts past under the Cassini spacecraft's gaze. The spoke-forming region of the B ring displays faint longitudinal variations in brightness, from left to right, a feature...

Phoebe's true nature is revealed in startling clarity in this mosaic of two images taken during Cassini's flyby on June 11, 2004. The image shows evidence for the emerging view that Phoebe may be a...
