Great Red Spot

Cratered terrain in the northern hemisphere of Ceres is seen in this image from NASA's Dawn spacecraft. The scene is dotted with small impacts among larger, more ancient craters.

This image shows examples of straighter, shorter, wider gullies that scientists on NASA's Dawn mission have found on the giant asteroid Vesta. The crater shown here is called Fonteia.

The southern hemisphere of Enceladus is seen in this polar stereographic map, mosaicked from the best-available Cassini and Voyager clear-filter images. The map is centered on the south pole and s...

NASA's Dawn spacecraft obtained this 3-D image of asteroid Vesta with its framing camera on Aug. 23 and 28, 2011 at a distance of 1,700 miles (2,740 kilometers). You will need 3D glasses to view th...

This view of the Cerean crater Victa was captured by NASA's Dawn spacecraft on Dec. 19, 2015. The steep-walled crater is approximately 19 miles (30 kilometers) in diameter, and was named for the Ro...

Cassini took this image of the ropy, taffy-like topography on Saturn's moon Enceladus as it soared above the icy moon on Feb. 17, 2005. This view, about 60 kilometers across (37 miles), shows seve...

This sequence of images shows a faint arc of material in Saturn's G ring, a tenuous ring outside the main ring system. These images were each taken about 45 minutes apart. During this time, the arc...

Cassini continues to uncover new wonders within the Saturn system with its discovery of two new moons orbiting between Mimas and Enceladus.

Artist's rendition of the Cassini spacecraft at Saturn. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Lab...

Huge clouds swirl through the southern latitudes of Saturn where the rings cast dramatic shadows.

Callisto was revealed by the Voyager cameras to be a heavily cratered and hence geologically inactive world.

In this closest-yet view of Ceres, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. This frame is from an animation of sequences tak...

This diagram illustrates the possible interior of Saturn's moon Enceladus based on a gravity investigation by NASA's Cassini spacecraft and NASA's Deep Space Network, reported in April 2014.

Rhea drifts in front of Saturn. The battered, icy moon is seen here near the western limb of the planet's northern hemisphere. This image was taken eight hours after The Rays of Rhea. The view loo...

This artist's rendering shows a cross-section of the surface and subsurface of Saturn's moon Titan, with a possible model for the structure of underground liquid reservoirs there.

This image from NASA's Dawn spacecraft shows the interior of the crater Datan, which is superimposed on the northwestern rim of the larger crater Geshtin. The area at right, above the rim of Datan,...

Prometheus is caught in the act of creating gores and streamers in the F ring.

Janus and Epimetheus continue to separate, following their orbital swap in January 2006. Until 2010, Janus will remain the innermost of the pair, whose orbits around Saturn are separated by only ab...

Saturn’s moon Dione drifts before the planet’s rings, seen here almost edge on.

The interior of Urvara Crater (101 miles, 163 kilometers wide) is featured in this image from NASA's Dawn spacecraft taken on June 2, 2016 at a distance of about 240 miles (385 kilometers) above th...

NASA's Dawn spacecraft obtained this image with its framing camera on Aug. 20, 2011. This image was taken through the camera's clear filter. The image has a resolution of about 260 meters per pixel.

This image depicts the dwarf planet Ceres, as seen from the Dawn spacecraft. It was taken 147,000 miles (237,000 kilometers) from Ceres on January 25, 2015, is part of a series of views representin...

The Cassini spacecraft imaged the surface of Saturn's moon Helene as the spacecraft flew by the moon on Jan. 31, 2011. This small moon leads Dione by 60 degrees in the moons' shared orbit. Helene ...

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 7, 2015, from a distance of 8,400 miles (13,600 kilometers).

Saturn's D ring may be faint and difficult to observe, but it rewards our patience. In this image, the Cassini spacecraft has captured some of the structure of the tenuous ring, appearing here as l...
