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...
Mimas Before Saturn
Wispy terrain reflects sunlight brightly in the lower left of this Cassini image of the northern latitudes of Saturn's moon Dione. These "wisps" are actually fractures on the trailing hemisphere of...
The prominent crater Telemachus sits within the northern reaches of Ithaca Chasma on Saturn's moon Tethys. Ithaca Chasma is an enormous rift that stretches more than 1,000 kilometers (620 miles) f...
Crater and Canyon
Several whirling storms churn through this scene from Saturn's atmosphere, obtained by the Cassini spacecraft. It is common on Saturn to see bright rings around dark atmospheric vortices, as in th...
A scalloped look is created in the edges of the Keeler Gap in Saturn's outer A ring as the moon Daphnis orbits in the gap. Daphnis (8 kilometers, or 5 miles across) is the bright spot in the narro...

Appearing like a freckle on the face of Saturn, a shadow from the moon Enceladus blemishes the planet just below the ringplane in this Cassini spacecraft image. Enceladus is not shown here. This v...
This composite is a mosaic comprising four individual NAVCAM images taken from 19 miles (31 kilometers) from the center of comet 67P/Churyumov-Gerasimenko on Nov. 20, 2014. The image resolution is ...
Dione's shadow is elongated as it is cast onto the round shape of Saturn. The moon is not visible here. This view looks toward the northern, sunlit side of the rings from just above the ringplane....
Dione's Distorted Shadow
Fresh from an encounter with Saturn's F ring, the moon Prometheus continues in its orbit. The gravity of potato-shaped Prometheus (86 kilometers, or 53 miles across) periodically creates streamer-...
On His Merry Way
With the icy rings between them, Dione and Tethys each show off the prominent features for which they are known. Dione, beyond the rings, displays wispy fractures that adorn its trailing side. Teth...

This image of Vibidia AV-L-20, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.

Saturn's B ring is spread out in all its glory in this image from Cassini. Scientists are trying to better understand the origin and nature of the various structures seen in the B ring. Saturn's B...
Titan's fast-rotating atmosphere creates circumpolar bands in the north. The Cassini spacecraft acquired this view of the smoggy moon following a flyby of Titan (5,150 kilometers, or 3,200 miles a...
Looking up toward Saturn's southern hemisphere, the Cassini spacecraft pictures a pair of the planet's moons orbiting in the distance. Tethys and Rhea orbit in the plane of the planet's rings, but...
Beyond Saturn's South
This mosaic of images from NASA’s Cassini spacecraft shows three fan-like structures in Saturn's tenuous F ring. Such "fans" suggest the existence of additional objects in the F ring. From right t...
Multiple F-Ring 'Fans'
Prometheus pulls material from the tortured F ring in this highly detailed view. The aftereffects of the moon's other recent encounters with the ring are visible above as dark channels in the inner...
Basking in sunlight, Enceladus looks peaceful and quiet while unseen jets of vapor and icy particles shoot from the south polar terrain of this active moon. The jets can't be seen here, but to wat...
A close-up view of the Keeler Gap, which is near the outer edge of Saturn's main rings, shows in great detail just how much the moon Daphnis affects the edges of the gap.
This fanciful view spies the Saturnian moons, Dione and Enceladus, from just beneath the ringplane. Enceladus (505 kilometers, or 314 miles across) is on the near side of the rings with respect to ...
Dione and Enceladus
The bright streaks visible in these Cassini images taken during Saturn's August 2009 equinox are exciting evidence of a constant rain of interplanetary projectiles onto the planet's rings. Objects...
