Io in Eclipse

The terminator nearly covers the south pole of Saturn and its stormy vortex in darkness. As the southern hemisphere moves toward winter in the planet's 29-year orbit, darkness eventually will con...

This stereo view of Iapetus was created by combining two Cassini images, which were taken one day apart. The view serves mainly to show the spherical shape of Iapetus and some of the moon's topogra...

Phoebe's Radiation June 23, 2004 Full-Res: PIA06402 This image shows thermal radiation from the day and night sides of Saturn's mo...

Polar Stratosphere August 16, 2004 Full-Res: PIA06470 This narrow angle ultraviolet image probes the high atmosphere above Saturn's s...

Close up detail focusing on a smooth region on the 'base' of the 'body' section of comet 67P/Churyumov-Gerasimenko.

Saturn's moon Mimas peeks out from behind the night side of the larger moon Dione in this Cassini image captured during the spacecraft's Dec. 12, 2011, flyby of Dione. Dione is 698 miles, or 1,123...

This global color mosaic of Saturn's moon Iapetus was produced from images taken by NASA's Cassini spacecraft during its first 10 years exploring the Saturn system.

This is a collection of the most detailed images of deep-level clouds obtained by the visual and infrared mapping spectrometer onboard the Cassini spacecraft. Images were obtained at 5.1 micron wa...

The Cassini spacecraft looks past the cratered south polar area of Saturn's moon Rhea to spy the moon Dione and the planet's rings in the distance. Dione's "wispy" terrain can be seen on the trail...

This illustration shows an inside view of the NASA's Dawn spacecraft.

+ View Labeled Version This image collage features Saturn and the moons Titan, Enceladus, Dione, Rhea and Helene, which will be studied in the extended mission. Credit: NASA/JPL/Space Science Ins...

Against a background of muted atmospheric bands in Saturn's northern hemisphere, Mimas forges onward in its orbit around the Ringed Planet. Aside from the large crater Herschel (139 kilometers, or...

Titan's surface and atmospheric features are shown here in this processed, visible-light image taken by Cassini. Cassini's visible-light spectral filter is sensitive to a broad range of light, fro...

Specially designed Cassini orbits place Earth and Cassini on opposite sides of Saturn's rings, a geometry known as occultation. Cassini conducted the first radio occultation observation of Saturn's...

Enceladus' intriguing south-polar jets are viewed from afar, backlit by sunlight while the moon itself glows softly in reflected Saturn-shine.

The rim of Hamori Crater on Ceres is seen in the upper right portion of this image, which was taken by NASA's Dawn spacecraft. Hamori is located in the southern hemisphere of Ceres and measures 37 ...

+ Annotated version This false-color view of Saturn's moon Mimas from NASA's Cassini spacecraft accentuates terrain-dependent color differences and shows dark streaks running down the sides of som...

With streaks of icy material thrown in many directions, a huge ray crater stretches across nearly half of the leading hemisphere of Saturn's moon Rhea. With the sun almost directly behind the spac...

This image of asteroid Vesta from NASA's Dawn spacecraft shows a region of the surface that is rather smooth in appearance which is located in Vesta's Marcia quadrangle, near the Vestan equator.

These images from NASA's Dawn spacecraft shows a region around the asteroid Vesta's equatorial troughs with two different resolutions. More details are visible in the right-hand image such as small...

From beneath the ringplane, the Cassini spacecraft takes stock of Saturn's southern skies and peeks through the rings and beyond their shadows at the northern latitudes. The image was taken by th...

This is an artists concept of Cassini during the Saturn Orbit Insertion (SOI) maneuver, just after the main engine has begun firing. The spacecraft is moving out of the plane of the page and to the...

This enhanced-color mosaic of Saturn's icy moon Tethys shows a range of features on the moon's trailing hemisphere. 

The ghostly spokes in Saturn's B ring continue to put on a show for the Cassini spacecraft cameras in this recent image. The spokes, believed to be a seasonal phenomenon, are expected to disappear ...

Cassini surveys a bright landscape coated by dark material on Iapetus. This image shows terrain in the transition region between the moon's dark leading hemisphere and its bright trailing hemispher...
