Io in Eclipse
Scarred and battered Rhea fills the Cassini spacecraft's view. Notable here is the sharp relief of steep crater walls near the terminator. Icy Rhea (1,528 kilometers, or 949 miles across) is Satur...
The shadow of the moon Epimetheus stretches across the B ring in this image taken by Cassini as Saturn approaches its 2009 equinox. The novel illumination geometry created as Saturn approaches its...
Shadow on Bright B Ring
This composite image is a simulated true color image of part of asteroid Vesta's northern region, which contains the 'snowman craters.' Images such as these greatly help the process of understandin...
'Snowman Craters' in Simulated True Color
What looks like a pair of Saturnian satellites is actually a trio upon close inspection.
The shadow of Saturn cuts across the rings in this recent Cassini spacecraft image.
In this image of the F ring, taken shortly after its ring particles encountered the shepherd moon Prometheus, the disruption to the ring caused by the moon is evident. The bright core of the ring ...
In this 20-second exposure, a meteor lights up the sky over the top of a mountain ridge near Park City, Utah.
Falling from Space
NASA's Dawn spacecraft obtained this view of shadowed craters near Ceres' north pole at a distance of about 240 miles (385 kilometers) above the surface on May 28, 2016.
Dawn LAMO Image 153
This image, taken by NASA's Dawn spacecraft, shows dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was take...

The faint dot in the upper right is Neptune's tiny moon Hippocamp.
Neptune's Moon Hippocamp
Viewed nearly edge-on, Saturn's rings appear dark and pencil-thin against the backdrop of the planet's swirling clouds. Notable here are the shadows cast by the rings onto the northern hemisphere,...
Southern Face of Saturn
Saturn's rings appear strangely warped in this view of the rings seen through the upper Saturn atmosphere. The atmosphere acts like a lens in refracting (bending) the light reflected from the ring...
Bending the Rings
Saturn's moon Enceladus reflects sunlight brightly while the planet and its rings fill the background of this Cassini view.
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 ...
Halfway to Southern Winter
Similar to many of the small, inner moons of Saturn, Prometheus points its long axis at Saturn as if giving us directions to the planet.
Pointing Toward Saturn
The "H"-shaped region Fensal-Aztlan is faintly visible on Saturn's murky moon Titan in this enhanced clear-filter view from Cassini. While most of the light passing through the clear filters is vi...
The Land Beneath the Murk
The waxing gibbous Moon rises over the Wasatch Mountains near Salt Lake City on April 17, 2019.
A Layered Moonrise
The thin shadow of the moon Pandora cuts across Saturn's narrow F ring. As Saturn approaches its August 2009 equinox, the planet's moons cast shadows onto the rings. To learn more about this speci...
Slender Slice of Shadow
Peering over the shoulder of giant Saturn, through its rings, and across interplanetary space, NASA's Cassini spacecraft spies the bright, cloudy terrestrial planet, Venus. The vast distance from S...
Earth's Twin Seen From Saturn
This enhanced-color image was created by combining three images taken through ultraviolet, violet and green filters on July 12, 1981. Several changes were apparent in Saturn's atmosphere since Voya...
Saturn Color Variation
Titan shines beyond the rings like a brilliant ring of fire, its light gleaming here and there through the gaps in Saturn's magnificent plane of ice. Titan (5,150 kilometers, or 3,200 miles across...
Rings Occulting Titan
The month of January is named for the mythical Roman god Janus, who guarded the gate of heaven. Cassini spied the heavily cratered, irregularly shaped moon of Saturn as it glided along in its orbit...
The shadow of Tethys drifts across the face of Saturn. Nearby, shadows of the planet's rings form a darkened band above the equator. This view looks toward Saturn from a vantage point 63 degrees n...
This image of Aricia AV-L-11, 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.
This geological map covers a portion of Pluto's surface that measures 1,290 miles (2,070 kilometers) from top to bottom, and includes the vast nitrogen-ice plain informally named Sputnik Planum and...
