From just outside the faint edge of Saturn's F ring, the moon Pandora keeps watch over her fine grained flock. The outer flanks of the F ring region are populated by ice particles approaching the s...
Keeping Things In Check
Giant craters like the one seen in this view deform the shape of Hyperion, making it the largest irregularly shaped body in the Saturn System. The moon has such a low density -- about half that of...
This picture of Venus was taken by the Galileo spacecrafts Solid State Imaging System on February 14, 1990, at a range of almost 1.7 million miles from the planet.

In this image, Saturn's fascinating meteorology manifests itself in a "string of pearls" formation, spanning over 60,000 kilometers (37,000 miles). Seen in new images acquired by Cassini's visual ...
String of Pearls
Cassini peers through the murky orange haze of Titan to spy what are believed to be bodies of liquid hydrocarbons, two of them as large as seas on Earth, near the moon's north pole.

In addition to being evidence of past impacts, craters can serve another valuable scientific purpose.
This Cassini spacecraft view shows how the bright and dark regions on Iapetus fit together like the seams of a baseball. Some of the material that covers the moon's dark, leading side spills over i...
World of Contrast
This image shows the unexpected "hot spot" at Saturn's north pole. Scientists were surprised to find that the north pole, despite being in winter darkness for more than a decade, is home to a hot, ...
Saturn's North Pole Hot Spot and Hexagon
Our robotic explorer Cassini regards the shadow-draped face of Saturn. This view looks toward the unilluminated side of the rings from about 14 degrees above the ringplane. In this viewing geometr...
Grace and Beauty
This image was taken during Cassini's third close approach to Titan on Feb. 15, 2005. The image was taken with the Cassini spacecraft narrow angle camera, through a filter sensitive to wavelengths...
Close Titan Flyby 3, Image #2
This close-up view shows an inner region of Saturn's C ring. It covers a radial location on the rings located approximately 78,000 to 80,500 kilometers (48,500 to 50,000 miles) from the center of t...
This frame from a movie shows that the brightest area on Ceres, located in Occator Crater, was one of the last features to be imaged as NASA's Dawn progressively built its map.
Ceres LAMO Coverage Map
As northern winter ends on Saturn and the Cassini spacecraft's view of the north pole improves, the swirls and eddies visible until now only in the south are gradually coming into view in the north...
Hoping for a Hex
Cassini's high-gain antenna is able to operate at S, X, Ka, and Ku-band frequencies. In addition to communications (X-band between Earth and orbiter, and S-band from probe to orbiter), radio scie...
The soft appearance of Dione's wispy terrains belies their true nature. They are, in fact, complex systems of crisp, braided fractures that cover the moon's trailing hemisphere. (See Dione's Surpr...
This image, taken by NASA's Dawn spacecraft, shows a small patch of bright material close to the northern rim of the giant crater Yalode, seen at lower left. Yalode is one of the largest impact bas...
Dawn LAMO Image 44
+ Unannotated Version This global map of Saturn's moon Mimas was created using images taken during Cassini spacecraft flybys, with Voyager images filling in the gaps in Cassini's coverage. The mo...
Map of Mimas - February 2010
Colorful new images from the Cassini spacecraft show that Saturn's northern hemisphere has a case of the blues. In the first image, the icy moon Mimas is set against a dazzling and dramatic portra...

This image from NASA's Dawn spacecraft shows part of the sharp, fresh rim of a large crater on asteroid Vesta. There is some bright material slumping towards the center of this crater but this is m...
Sharp Crater Rim with Dark Material and Boulders
Rhea, like many moons in the outer solar system, appears dazzlingly bright in full sunlight. This is the signature of the water ice that forms most of the moon's surface.

Rosetta's Target Up Close
From high above Saturn's northern hemisphere, NASA's Cassini spacecraft gazes over the planet's north pole, with its intriguing hexagon and bullseye-like central vortex.
The dramatic Ithaca Chasma carves an enormous gash for more than 1,000 kilometers (620 miles) across Saturn's moon Tethys. Tethys is 1,071 kilometers (665 miles) across. Stretching across the top ...
