+ 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...

This image from NASA's Dawn spacecraft, taken June 7, 2016, shows part of Lono Crater (at bottom) within the giant Yalode impact basin on Ceres.

Saturn's largest moon, Titan, peeks out from under the planet's rings of ice. This view looks toward Titan (5,150 kilometers, or 3,200 miles across) from slightly beneath the ringplane. The dark E...

The rings cannot hide the ragged, icy crescent of Rhea, here imaged in color by the Cassini spacecraft. The second-largest moon of Saturn shines brightly through gaps in the rings. Rhea (1,528 kil...

Io Color Eclipse

NASA's Dawn spacecraft obtained this view of Azacca Crater on Ceres. The rim of this crater has terraces descending from its rim down to its floor. The crater's floor is relatively free of large im...

These three images, created from Cassini Synthetic Aperture Radar (SAR) data, show the appearance and evolution of a mysterious feature in Ligeia Mare, one of the largest hydrocarbon seas on Saturn...

Rhea has been heavily bombarded by impacts during its history. In this Cassini image the moon displays what may be a relatively fresh, bright, rayed crater near Rhea's eastern limb. Rhea is 1,528 k...

This is the sharpest image of Saturn's temperature emissions taken from the ground; it is a mosaic of 35 individual exposures made at the W.M. Keck I Observatory, Mauna Kea, Hawaii on Feb. 4, 2004....

The young rays of Mena crater contrast brightly against the surrounding surface, though the rays will gradually fade with time. 

These are two raw, or unprocessed, images taken by the Cassini spacecraft during its close flyby of Saturn's moon Iapetus on September 10. For more information about the Cassini-Huygens mission vis...

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.

Saturn's moon Mimas has many large craters, but its Herschel crater dwarfs all the rest. This large crater 130 kilometers wide (80 miles) has a prominent central peak, seen here almost exactly on t...

Saturn's richly dynamic atmosphere rewards viewers with unique and fascinating structures with every new observation. Here, the Cassini spacecraft uses the near-infrared filters on its wide-angle ...

This picture is a composite of 30 images from ESA's Huygens probe. They were taken from an altitude varying from 13 kilometers down to 8 kilometers when the probe was descending towards its landing...

Rhea's Battered Surface November 9, 2004 Full-Res: PIA06516 This view of Saturn's second-largest moon, Rhea (1,528 kilometers, or ...

 “This is an adaption of the Cassini Raw Image W00086402."

This is the original Voyager "Blue Movie" (so named because it was built from blue filter images). It records the approach of Voyager 1 in 1979 during a period of over 60 Jupiter days taking images...

Cassini acquired this view of Titan on April 13, 2007, following a flyby of the Mercury-sized moon. Titan's equatorial dark regions are visible in this view, along with faint, dark lineaments (line...

This image of a boulder field near Ceres' Occator Crater's eastern rim was obtained by NASA's Dawn spacecraft on June 9, 2018 from an altitude of about 30 miles (48 kilometers).

A grandiose gesture of gravity, Saturn's icy rings fan out across many thousands of kilometers of space. The moon Pan (26 kilometers, or 16 miles across) dutifully follows its path, like the billio...

This image, taken on June 7, 2015 by NASA's Dawn spacecraft, shows a portion of the southern hemisphere of Ceres from an altitude of 2,700 miles (4,400 kilometers). The crater at the lower left is ...

The shepherd moons Prometheus and Pandora drive the quirky F ring in its circuit of Saturn, while Mimas lurks in the distance. This view looks toward the unilluminated side of the rings from about...

Saturn's north pole hexagon, seen here in an image from the Cassini spacecraft, has been around for awhile. It was seen in Voyager images in the early 1980s, in ground-based telescopic images in th...

Is Dione (698 miles or 1123 kilometers across) suddenly larger than Rhea (949 miles or 1527 kilometers across)?
