Great Dark Spot

This image, taken by NASA's Dawn spacecraft, shows a portion of Ceres at mid-latitudes from an altitude of 915 miles (1,470 kilometers). The image, with a resolution of 450 feet (140 meters) per pi...

These four images are among thousands NEAR Shoemaker acquired during several low-altitude passes over Eros from January 25-28, 2001.

The complete remote sensing pallet is lowered by technicians from the Jet Propulsion Laboratory (JPL) of the California Institute of Technology and mated at the interface with the Cassini spacecraf...

Cassini images of Saturn's dynamic atmosphere, like this detailed view, will be combined with data from the spacecraft's two infrared-sensing instruments (the Visible and Infrared Mapping Spectrome...

A small moon travels its circuit just outside the main rings of Saturn. Epimetheus (116 kilometers, 72 miles across) is absolutely dwarfed by the giant planet. This view looks toward the unillumin...

This natural color image of the limb of Triton was taken early in the morning of Aug. 25 1989, when the Voyager 2 spacecraft was at a distance of about 210,000 kilometers (128,000 miles) from the i...

Fragments of comet Shoemaker-Levy 9 approaching Jupiter in 1994.

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 16, 2015, from a distance of 4,500 miles (7,200 kilometers).

Slumping features and landslides can be clearly seen near the base of the largest scarp in this image from NASA's Dawn spacecraft. Some of the hummocky terrain near the scarps is probably due to la...

An extreme false-color view of Tethys reveals a surface detail not visible in a monochrome view taken at the same time. The false-color view shows a color transition from the moon's Saturn-facing ...

Using a special spectral filter, the high-resolution camera aboard NASA's Cassini spacecraft was able to peer through the hazy atmosphere of Saturn's moon Titan.

Three large meteorite impact craters, with diameters that range from 37 to 50 km (23 to 31 miles), are seen in this image of the Lavinia region on Venus.

Prometheus shows up bright in this image of the dark side of the rings. The bright band that appears above Prometheus in this image is the Cassini division separating the (very dark) B ring and th...

This global digital map of Saturn's moon Dione was created using data taken by the Cassini spacecraft, with gaps in coverage filled in by NASA's Voyager spacecraft data. The map is an equidistant p...

This excellent view of the faint E ring -- a ring feature now known to be created by Enceladus -- also shows two of Saturn's small moons that orbit within the ring, among a field of stars in the ba...

The Cassini spacecraft spots a couple of large, wedge-shaped spokes in Saturn's B ring. These spokes are similar in appearance to those seen by the Voyager spacecraft (see Saturn's rings - high r...

A large, bright and complex convective storm that appeared in Saturn's southern hemisphere in mid-September 2004 was the key in solving a long-standing mystery about the ringed planet. Saturn's at...

South Pole on Saturn July 12, 2004 Full-Res: PIA05414 Details observed in Saturn¿s south polar region demonstrate that this area ...

A great vortex rolls through high southern latitudes on Saturn, whirling twisted contours into the clouds. The ringed planet's uppermost clouds are thought to be composed largely of ammonia ice ove...

Saturn and Dione regard Enceladus -- the object their gravitational tug-of-war. Dione (1,126 kilometers, or 700 miles across) is seen next to Saturn here. Enceladus (505 kilometers, or 314 miles ac...

The Cassini spacecraft captures Janus in the foreground, with Dione in the distance beyond. The image was taken two hours after Hiding Dione, in which Cassini imaged Dione beyond the rings. Janus...

With kaleidoscopic forms and hues, these two false-color views from NASA's Cassini spacecraft show the patterns that come and go in the course of one Saturn day within the huge storm in the planet'...

This high resolution image of the icy crust of Europa, one of Jupiter's moons, reveals a surface criss-crossed by multiple sets of ridges and fractures. 

+ View Labeled Version   High-resolution Cassini images show an astonishing level of structure in Saturn's Cassini Division, including two ringlets that were not seen in NASA Voyager spacecraft i...

This view 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 on Enceladus...
