As Titan Turns

Three of Titan's major surface features - dunes, craters and the enigmatic Xanadu - appear in this radar image from NASA's Cassini spacecraft. The hazy bright area at the left that extends to the l...

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Mojave" site, where its drill collected the mission's second taste of Mount Sharp.

This view from NASA's Dawn spacecraft, taken on June 6, 2016, shows Takel Crater (at top left) on Ceres. Takel is 14 miles (22 kilometers) wide and exhibits streaks of bright material on its walls.

The oblate shape of Mimas is presented in this Cassini spacecraft image. The moon appears flattened at the poles with an equatorial bulge. To learn more about this small moon, see Not Quite Round....

The small moon Pan casts a short shadow on Saturn's A ring in this image taken as the planet approached its August 2009 equinox. Pan (28 kilometers, or 17 miles across) orbits in the Encke Gap of ...

Saturn's D ring--the innermost of the planet's rings--sports an intriguing structure that appears to be a wavy, or "vertically corrugated," spiral. This continuously changing ring structure provide...

This enhanced image, taken by the framing camera instrument aboard NASA's Dawn spacecraft on July 9, 2011, views the south polar region of this giant asteroid.

This 3-D image shows the topography of Vesta's densely cratered terrain obtained by the framing camera instrument aboard NASA's Dawn spacecraft on August 6, 2011. You need 3D glasses to view this i...

This image of a small boulder on Ceres was obtained by NASA's Dawn spacecraft on June 10, 2018 from an altitude of about 24 miles (38 kilometers).

In a special double flyby early next week, NASA's Cassini spacecraft will visit Saturn's moons Titan and Dione within a period of about a day and a half, with no maneuvers in between. A fortuitous ...

As Cassini continues its weekly ring-grazing orbits, diving just past the outside of Saturn's F ring, it is tracking several small, persistent objects there. 

Saturn's moon Rhea is an alien ice world, but in this frame-filling view it is vaguely familiar. Here, Rhea's cratered surface looks in some ways similar to our own Moon, or the planet Mercury. Bu...

The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, is centered at 180 degrees east longitude. 

This image of Ceres from NASA's Dawn spacecraft was taken at an oblique viewing angle relative to the surface. The crater to the upper right is named Juling which displays prominent spurs of compac...

The Cassini spacecraft gazes toward the multiple strands of the ever-changing F ring, also sighting Atlas at its station just beyond the A ring edge. A few faint background stars are visible in th...

This spectacular view is a mosaic of four high resolution images taken by the Cassini spacecraft narrow angle camera on Feb. 16, 2005, during its close flyby of Saturn's moon Enceladus. The view i...

This montage of two views is published by the Cassini team to mark the 10th anniversary of the Phoebe flyby.

Curving wakes perturb the edges of the Encke Gap in Saturn's A ring. The culprit in their creation is the flying saucer-shaped moon Pan, shining brightly within the gap. Ahead of Pan (26 kilometer...

NASA's Cassini spacecraft captures a composite near-true-color view of the huge storm churning through the atmosphere in Saturn's northern hemisphere.

This close-up view is Cassini's best look yet at Saturn's tenuous innermost D ring. The narrow ringlet visible here is named "D68" and is the innermost discrete feature in the D ring. The image als...

On July 19, 2013, in an event celebrated the world over, NASA's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings -- and, in the ba...
