Dark and sharply defined ring shadows appear to constrict the flow of color from Saturn's warmly hued south to the bluish northern latitudes. Scientists studying Saturn are not yet sure about the ...

Rings Around Saturn
Although this image is centered on the Saturn-facing hemisphere of Titan, here the sun illuminates mainly the trailing hemisphere of Saturn's largest moon. The image was taken with the Cassini sp...
Saturn's View of Titan's Trailing Hemisphere
A pair of moons, Pandora and Prometheus, continue their shepherding duties near Saturn's thin F ring. Pandora (81 kilometers, or 50 miles across) orbits outside the F ring and, with the inner shep...
A Pair of Shepherds
The complex structure of Saturn's quirky F ring is unfurled in this mosaic made up of images taken by NASA's Cassini spacecraft. The mosaic covers 255 degrees of longitude within the F ring, which...
Unrolling the F-ring
This false-color Cassini mosaic of Saturn's moon Enceladus captures in a single view, much of the frigid moon's diverse geology.
Old and New Again
On Dec. 13, 1972, scientist-astronaut Harrison H. Schmitt is photographed standing next to a huge, split lunar boulder during the third Apollo 17 extravehicular activity (EVA) at the Taurus-Littrow...
Apollo 17 Extravehicular Activity
Mimas and Pandora remind us of how different they are when they appear together as in this Cassini spacecraft image. Although they are both moons of Saturn, Pandora's small size means that it lac...
Two Moons Passing in the Night
+ See Annotated Version + High Resolution Version This artist’s concept shows a possible model of Titan’s internal structure that incorporates data from NASA’s Cassini spacecraft. In this model, ...
Layers of Titan -- Unannotated
This raw image of Saturn's moon Dione taken by NASA's Cassini spacecraft shows the fractured region known as "wispy terrain." The image was obtained on Dec. 20, 2010, from a distance of about 107,0...
Titan Vs. Mars October 28, 2004 Full-Res: PIA06990 This image compares streaked terrain on Titan and Mars. At left is an image from Cassi...

NASA's Dawn spacecraft obtained this image of a young and old crater at the night and day boundary on asteroid Vesta. The image has a resolution of about 260 meters per pixel.
Young and Old Crater at the Night and Day Boundary on Vesta
A bright arc within Saturn's faint G ring holds a tiny gift. A small moonlet is just visible as a short streak near the ansa of the G ring arc in the top of two versions of the same image. The sec...
NASA's Cassini spacecraft captured this view of Saturn's moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby on Dec. 6, 2015.
This image of a fracture network in Occator Crater on Ceres was obtained by NASA's Dawn spacecraft on July 1, 2018 from an altitude of about 29 miles (46 kilometers).
Fracture Network in Occator Crater
This lake is part of a larger image taken by the Cassini radar instrument during a flyby of Saturn's moon Titan on Sept. 23, 2006. It shows clear shorelines that are reminiscent of terrestrial lak...
Shorefront Property, Anyone?
The extreme contrast in this view of the unlit side of Saturn's rings is intentional. Contrast-enhanced views like this are used to look for spokes (the transient, ghostly lanes of dust seen in NAS...
On the Lookout for Spokes
NASA’s Cassini spacecraft captured a propeller-shaped disturbance in one of Saturn's rings created by a moon that is too small to be seen here. The moon, likely about a kilometer (half a mile) acr...
Tracking a Propeller
This image, created using data from NASA's Dawn spacecraft, shows craters (blue markings) called 'cold traps'. These shadowed craters may have been collecting ice for billions of years because they...
Shadowed Craters on Ceres
“This is a view of crescent Saturn, based on the raw image from Cassini on March 12, 2014."
Crescent Saturn View by Stephane Calonnec
The rich dynamics of Saturn's F ring are on display in this image taken by the Cassini spacecraft. Most of the features seen here are believed to be due to the ring's interactions with its shepherd...
Ceres' densely cratered landscape is revealed in this image taken by the framing camera aboard NASA's Dawn spacecraft. The craters show various degrees of degradation. The youngest craters have sha...
Dawn LAMO Image 84
A lone moon coasts along in this view, which was taken from less than a degree below Saturn's sunlit ringplane. The rings are squashed into a narrow band from this viewing angle, foreshortening all...
Four moons huddle near Saturn's multi-hued disk. The coloration of the planet's northern hemisphere has changed noticeably since the Cassini spacecraft's arrival in orbit in mid-2004. Imaging sci...
