Io Color Eclipse

The Cassini spacecraft has obtained new images of Saturn's auroral emissions, which are similar to Earth's Northern Lights. Images taken on June 21, 2005, with Cassini's ultraviolet imaging spectro...

This image of Ceres, taken by NASA's Dawn spacecraft, features several craters with bright material within and around them. The image is centered on terrain near the equator of Ceres and faces sout...

The low angle of the sun over Tethys' massive canyon, Ithaca Chasma (near the terminator, at right), highlights the contours of this enormous rift.

This image shows a high-resolution heat intensity map of part of the south polar region of Saturn's moon Enceladus, made from data obtained by NASA's Cassini spacecraft.

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 22, 2015, from a distance of 3,200 miles (5,100 kilometers) with a resolution of 1,600 feet (480 meters) per pixel.

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Floronia quadrangle, in Vesta's northern hemisphere; distinct sinuous grooves are visible around the rim of the crater.

The south pole of the giant asteroid Vesta reveals cliffs that are several miles or kilometers high, deep grooves, and craters. This oblique view is from NASA's Dawn spacecraft.

Saturn's moon Janus obscures part of the planet's A ring as the Cassini spacecraft looks toward the main rings and the thin F ring. Janus (179 kilometers, or 111 miles across) appears as a dark ov...

It's hard not to speculate about the origins of the narrow, dark features seen in Cassini's new images of Titan's surface. They tantalize the viewer, resembling the dark channels seen elsewhere ...

This view from NASA's Dawn spacecraft shows terrain in the southern hemisphere of Ceres. Most of the image is the impact crater named Annona (37 miles, 60 kilometers across); the smaller, prominent...

This image from NASA's Dawn spacecraft shows the northeastern rim of Urvara Crater on Ceres at lower left. To the right of the crater, the long, narrow feature that appears to jut out toward the no...

Comet Siding Spring makes a close pass by Mars and Mars in October 2014.

The shepherd moon Pan orbits Saturn in the Encke gap while the A ring surrounding the gap displays wave features created by interactions between the ring particles and Saturnian moons. Pan (17 mil...

The cameras on NASA's Cassini spacecraft captured this rare look at Earth and its moon from Saturn orbit on July 19, 2013. Taken while performing a large wide-angle mosaic of the entire Saturn rin...

Saturnian Hurricane October 7, 2004 Full-Res: PIA06493 This close-up view shows lots of atmospheric detail, including a dark storm an...

Merging Saturnian Storms

Although the Huygens probe has now pierced the murky skies of Titan and landed on its surface, much of the moon remains for the Cassini spacecraft to explore. Titan continues to present exciting pu...

Beyond the Rings: Mimas August 5, 2004 Full-Res: PIA05428 Looking beyond Saturn's magnificent rings, Cassini caught a glimpse of t...

Cassini images reveal the existence of a faint arc of material orbiting with Saturn's small moon Anthe. The moon is moving in a counterclockwise direction in this perspective, and is about to reac...

The Cassini spacecraft spies two types of waves in Saturn's A ring: a spiral density wave on the left of the image and a more pronounced spiral bending wave near the middle. See Two Kinds of Wave ...

+ Unannotated version Five images of Saturn's rings, taken by NASA's Cassini spacecraft between 2009 and 2012, show clouds of material ejected from impacts of small objects into the rings. Clockwi...

In this view, individual layers of haze can be distinguished in the upper atmosphere of Titan, Saturn’s largest moon.

Saturn's moon Prometheus chases Pandora in this Cassini view, but the outcome of their race has already been decided by gravity. Prometheus orbits closer to Saturn and thus moves faster than does P...

NASA is exploring our solar system and beyond to understand the workings of the universe, searching for water and life among the stars.

These two false-color views from NASA's Cassini spacecraft show detailed patterns that change during one Saturn day within the huge storm in the planet's northern hemisphere.
