Io Color Eclipse
Saturn's biggest and brightest moons are visible in this portrait by Cassini. Titan (5,150 kilometers, or 3,200 miles across) is Saturn's largest moon and appears at the lower left. Note that some...
As one NASA spacecraft sailed past the distant ice world of Pluto, collecting never-before-seen vistas and invaluable science data, another spacecraft turned its gaze in that direction from its out...

As it departed its encounter with Saturn's moon Dione, Cassini sailed above an unreal landscape blasted by impacts. The rising Sun throws craters into sharp contrast and reveals steep crater walls...
The dark side of the ringplane glows with scattered light, including the luminous F ring, which shines like a rope of brilliant neon. Below, Dione (1,126 kilometers, or 700 miles across) presents a...
Saturn's Night Lights
As Cassini sped away from its close encounter with Saturn's moon Hyperion on Sept. 26, 2005, it took this parting shot of the battered moon's shadowy limb. The image was taken in visible light wit...

Herding the Rings
Saturn's small moons Atlas, Prometheus, and Epimetheus keep each other company in this Cassini spacecraft image of the planet's night side.
The slim crescent of Ceres smiles back as the dwarf planet awaits the arrival of an emissary from Earth. This image was taken by NASA's Dawn spacecraft on March 1, 2015.

Two small portions of Saturn's F ring shine brilliantly in scattered sunlight as Rhea floats in the distance beyond. Rhea is 1,528 kilometers (949 miles) across. This view looks toward the unillu...
This image was taken by NASA's Dawn spacecraft of dwarf planet Ceres on Feb. 19 from a distance of nearly 29,000 miles (46,000 kilometers). It shows that the brightest spot on Ceres has a dimmer co...

Until 1994, the optically opaque atmosphere of Titan completely hid the satellite's surface from view. In 1994, the Wide Field-Planetary Camera on the Hubble Space Telescope provided the first glim...
The moon Iapetus, like the "force" in Star Wars, has both a light side and a dark side.

Mawrth Vallis is one of the oldest valleys on Mars, formed in and subsequently covered by layered rocks, from beneath which it is now being exhumed.

This image shows an updated map of Saturn's icy moon Enceladus, generated by the Cassini imaging team. The map incorporates new images taken in 2008, with better image processing techniques. Comp...
Map of Enceladus -- October 2009
The Cassini spacecraft views the rugged surface of Mimas -- half lit by the Sun, and half lit by reflected light from Saturn. On the sunlit western limb lies the great Herschel impact crater. The ...

This low resolution view of Tethys provides scientists with useful information about the moon's surface properties, regardless of the image's small size. The view, which was taken using an ultrav...
Recent images of features in Saturn's C ring called "plateaus" reveal a streaky texture that is very different from the textures of the regions around them.
