This Cassini view of Saturn's moon Tethys shows several large craters near the moon's eastern limb. These craters have fanciful names such as Phemius, Polyphemus and Ajax. The moon's massive rift-l...
Slice of Tethys
A vertical corrugation in Saturn's almost transparent D ring can give rise to brightness variations. In this graphic representation, the diagonal lines (or arrows) correspond to lines of sight thro...
D Ring Sight Lines
Gazing across the ringplane, the Cassini spacecraft spots a Saturn-lit Mimas and the tiny Trojan moon Helene. Only the bright crescent on Mimas' eastern limb is lit by the Sun; the moon's night sid...
Small Worlds of Saturn
Ithaca Chasma rips across Tethys from north to south near the center of this view. The moon's western limb is flattened, indicating the rim of the giant impact basin Odysseus. The dark, east-west ...
Band Becomes Bright
This synthetic-aperture radar (SAR) image was obtained by NASA's Cassini spacecraft on July 25, 2016, during its "T-121" pass over Titan’s southern latitudes. This view was produced using the same ...
The 'Xanadu Annex' on Titan (Denoised)
The battered moon Epimetheus is dwarfed by Saturn in this image which shows a fraction of the planet's northern hemisphere. This view looks toward the trailing hemisphere of Epimetheus (113 kilome...
In this fabulous close-up, Cassini peers directly through regions of the A, B and C rings (from top to bottom here) to glimpse shadows of the very same rings cast upon the planet's atmosphere. Near...
Looking Through the Rings
The shadows of Saturn's rings edge ever farther southward as Saturn creeps towards southern winter (or northern summer). Saturn is now almost exactly halfway between its equinox (August 2009) and ...

Saturn's Two-Face Moon July 15, 2004 Full-Res: PIA06100 The moon with the split personality, Iapetus, presents a puzzling appearan...
Saturn's Two-Face Moon
This view of Titan's south pole reveals the intriguing dark feature named Ontario Lacus and a host of smaller features dotting the south polar region. The true nature of this feature, seen here at...
Land of Lakes?
NASA's Cassini spacecraft successfully completed its Oct. 1 flyby of Saturn's moon Enceladus, capturing these raw, unprocessed images of the moon and its dramatic plumes of water vapor and ice. Th...
Enceladus Flyby E-14 (Raw Image #5)
The ringed planet sits in repose, the center of its own macrocosm of many rings and moons and one artificial satellite named Cassini. Mimas (397 kilometers, or 247 miles across) is visible at upper...
Perspective on Saturn
This image from NASA's Dawn spacecraft shows a part of Vesta's northern hemisphere, which is mostly in darkness. Since Dawn's arrival at asteroid Vesta the sun has not illuminated Vesta's most nort...

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.
Titan's Subsurface Reservoirs -- Annotated
Titan's atmosphere makes Saturn's largest moon look like a fuzzy orange ball in this natural color view from the Cassini spacecraft. Titan's north polar hood is visible at the top of the image, an...

The Cassini spacecraft looks toward the south pole of Enceladus, with a glimpse of Saturn's rings in the distance, during the spacecraft's close flyby Nov. 2, 2009. See Jet Blue to learn more abou...
Enceladus Before the Rings
During a distant flyby encounter with Enceladus, Cassini imaged the moon's wrinkled leading hemisphere. At the scale visible here, this region of the surface is generally devoid of impact craters, ...
The Cassini spacecraft shows a section of Saturn and its rings which includes a special treat made possible as the planet approaches its August 2009 equinox: the shadow of a moon cast on the rings....
Sampling Saturn and a Shadow
In this image, obtained by the framing camera on NASA's Dawn spacecraft, various craters are visible in the southern equatorial region of the giant asteroid Vesta.

Rhea transits the banded clouds of the Ringed Planet. The edge-on rings cast curved shadows onto Saturn's northern hemisphere. More subtle than the ring shadows, the zonal jet streams of Saturn str...
Saturn's moon Dione floats in the dark sky before Cassini in this anaglyph, or 3D image, taken during an encounter in late 2005. Images taken from slightly different directions allow construction o...
Eleven years in the life of the Sun, spanning most of solar cycle 23.
This view of Ceres, taken by NASA's Dawn spacecraft on December 10, shows an area in southern hemisphere of the dwarf planet.
