Radar mapping Titan

Shadows darken parts of some of Janus' large craters as Cassini takes a close look during its flyby of this Saturnian moon on March 27, 2012. See Profile of Janus and Blasted Janus for higher reso...

The bright arc within Saturn's G ring is shown truncated by the shadow of the planet at the bottom of this image.

This image of Aricia AV-L-11, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.

This Voyager 2 photograph of Titan, taken Aug. 23, 1981, from a range of 2.3 million kilometers (1.4 million miles), shows some detail in the cloud systems on this Saturnian moon. The southern hemi...

Titan emerges from behind Saturn, while Tethys streaks into view, in this colorful scene. Saturn's shadow darkens the far arm of the rings near the planet's limb. Titan is 5,150 kilometers (3,200 ...

The Cassini spacecraft spies the icy moon Mimas on the far side of Saturn's rings. The large crater Herschel gives the moon a flattened profile on its leading hemisphere, at left. This view looks ...

Ceres' Haulani Crater is shown in these views from NASA's Dawn spacecraft. These views reveal variations in the region's brightness, mineralogy and temperature at infrared wavelengths.

Mimas and the Rings October 26, 2004 Full-Res: PIA06506 This Cassini image shows a nearly half-full Mimas (a moon that is 398 kilo...

A movie sequence of Saturn's G ring over a full orbital revolution captures its single bright arc on the ring's inner edge.

Three impact craters of different sizes, arranged in the shape of a snowman, make up one of the most striking features on Vesta, as seen in this view from NASA's Dawn mission.

This closeup of asteroid Vesta from NASA's Dawn spacecraft shows small scale features such as grabens (linear depressions) which run parallel to and inside the troughs.

Lightning, crackles and pops August 5, 2004 Full-Res: PIA06417 The speckles in this graph are radio signals from lightning in Sat...

This is NASA InSight's second full selfie on Mars.

+ View Full Res These images were obtained by Cassini's radar instrument during a flyby on Oct. 2, 2007. The radar antenna was pointing toward Titan at an altitude of 975 kilometers (605 miles) du...

This image from NASA's Dawn spacecraft shows the dramatic-looking crater named Haulani on Ceres.

It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 miles (45,000 kilometers) away from the rings.

Cassini looks toward Tethys and its great crater Odysseus, while at the same time capturing veiled Titan in the distance (at left). Titan (5,150 kilometers, or 3,200 miles across) is shrouded in a...

On Dec. 4, 1973, NASA's Pioneer 10 spacecraft sent back images of Jupiter of ever-increasing size.

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...

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 ...

The Cassini spacecraft peeks through the murk of Titan's thick atmosphere in a search for clouds. Although there are no obvious cloud features in this view, bright cloud streaks have occasionally ...

This stereo anaglyph of Saturn's moon Enceladus shows an area that has undergone a very intriguing -- and in places puzzling -- sequence of events. The craters here are subdued, as seen elsewhere o...

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...

Saturn's Two-Face Moon July 15, 2004 Full-Res: PIA06100 The moon with the split personality, Iapetus, presents a puzzling appearan...

This image from NASA's Dawn spacecraft shows a raised mound material overlying the brighter material that makes up the floor of the south polar depression of asteroid Vesta. Many small scale crater...
