The northern and southern hemispheres of Enceladus are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager clear-filter images. [Editor's note: This capti...
Enceladus Polar Maps - North Pole - October 2009
This ancient crater on Ceres displays a flattened floor and a low, rounded central peak. NASA's Dawn spacecraft captured the scene on Jan. 2, 2016.

This low elevation image shows the G ring arc recently discovered by Cassini. This faint arc of material is maintained by a gravitational interaction with the moon Mimas. The image was taken in vi...
Although Saturn's moon Pan is absent from this image of the A ring's Encke Gap, the moon's handiwork is still displayed. The two ringlets seen in the gap are maintained by the gravitational action...
Linda Spilker, Cassini project scientist, and Jeff Cuzzi, Saturn ring specialist, stand in front of a section of the mural showing the ring particles with Saturn looming in the background.
NASA's Dawn mission has found that craters on Ceres show a diversity of shapes that provide important clues about the structure of Ceres' subsurface; shown here is Fejokoo, a polygonal crater.
NASA's Dawn spacecraft captured this tortured landscape just south of Ghanan Crater on Ceres on May 28, 2016, at a distance of about 240 miles (385 kilometers) above the surface.

Cassini's radar instrument obtained another in its series of north polar swaths of Titan on April 10, 2007. This image exposes more of the transition between the mid-latitudes and the polar area, ...
Titan (T28) Viewed by Cassini's Radar -- April 10, 2007
Light from the star Beta Crucis (Mimosa) breaks through the plane of the A ring in the center of this image of a stellar occultation. Several of Cassini's remote-sensing instruments use occultatio...

The Cassini spacecraft's current high-inclination orbit allows for some fantastic perspectives, like this shot of Saturn's south pole, which looks toward the rings beyond. The dark bullseye at the...
The small, bright crater Oxo on Ceres is featured in this image from NASA's Dawn spacecraft taken on Oct. 17, 2016. Oxo (6 miles, 10 kilometers in diameter) is located at mid-latitudes on Ceres and...

This global digital map of Saturn's moon Rhea was created using data taken during Cassini and Voyager spacecraft flybys. The map is an equidistant projection and has a scale of 667 meters (2,188 fe...
Map of Rhea - December 2005
Saturn's northern hemisphere is visible through its disc of icy particles. This view looks toward the sunlit side of the A ring from about 21 degrees below the ringplane. The image was taken in vi...
Behind the Veil
Looking like half of a figure eight, two of Saturn's moons appear conjoined in this Cassini spacecraft image. The moon Dione, at the top in the image, is actually closer to the spacecraft here. Ho...
