Tholin Formation in Titan's Upper Atmosphere

This celestial circle of light is produced by the glow of sunlight scattered through the periphery of Titan's atmosphere as the Sun is occulted by Titan. It is the sum of all the sunsets and sunris...

Cassini looks toward northern latitudes on Saturn and out across the ringplane. This infrared view probes clouds beneath the hazes that obscure the planet's depths in natural color views. This ima...

The Encke Gap, the broad, vertical dark band running down the center of this image, is maintained by the small moon Pan (not pictured). Pan also shepherds three ringlets, all of which appear here a...

NASA's Dawn spacecraft obtained this image of the giant asteroid Vesta with its framing camera on July 24, 2011. Dawn entered orbit around Vesta on July 15, and will spend a year orbiting the body.

Rhea's distinctive bright and relatively fresh-rayed crater lies in stark contrast to the large, round basin which sits along the terminator (the boundary between day and night) in this unmagnified...

This image shows a view across asteroid Bennu’s southern hemisphere and into space, and it demonstrates the number and distribution of boulders across Bennu’s surface.

Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons. See Haze Layers on Titan and Orange and Bl...

Saturn's moon Mimas appears near Saturn, dwarfed by its parent planet in this image. Mimas (246 miles, or 396 kilometers across) appears tiny compared to the storms clearly visible in far northern...

This artist's conception shows Titan's surface with Saturn appearing dimly in the background through Titan's thick atmosphere of mostly nitrogen and methane. The Cassini spacecraft flies overhead...

In a splendid portrait created by light and gravity, Saturn's lonely moon Mimas is seen against the cool, blue-streaked backdrop of Saturn's northern hemisphere. Delicate shadows cast by the rings...

As one NASA spacecraft sailed past the distant ice world of Pluto, collecting never-before-seen vistas and invaluable science data, another spacecraft turned its gaze in that direction from its out...

This image was taken during Cassini's extremely close encounter with Enceladus on Oct. 9, 2008. The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 9, 2008, a distance of a...

Saturn's frigid moon Titan has some characteristics that are oddly similar to Earth, but still slightly alien.

Titan emerges from behind Saturn, while Tethys streaks into view, in this colorful scene. Saturn's shadow darkens the far arm of the rings near the planet's limb. Titan is 5,150 kilometers (3,200 ...

A set of three parallel ridges was seen by the Cassini spacecraft's radar instrument during the latest Titan flyby on May 12, 2008. This combination is unlikely to be a coincidence -- the best expl...

NASA's Cassini spacecraft captured a three-dimensional view of the large Herschel Crater on Saturn's moon Mimas during its closest-ever flyby of the moon. Herschel Crater is 130 kilometers (80 mil...

This is an artist's concept of Saturn's rings and major icy moons. Saturn's rings make up an enormous, complex structure. From edge-to-edge, the ring system would not even fit in the distance be...

+ View Full Res This image was taken by NASA's Cassini spacecraft on April 14, 2012. The camera was pointing toward Enceladus at approximately 115 miles (185 kilometers) away. This image has not...

This set of images from NASA's Cassini spacecraft shows Saturn's moon Titan glowing in the dark. Titan was behind Saturn at the time, in eclipse from the sun. The image on the left is a calibrated,...

This is a narrow angle field-of-view artist's rendering from the bottom of a large ice crevasse on the surface of Phoebe, the least known of all the Saturnian satellites. Since Cassini will never ...

Plumes of icy material extend above the southern polar region of Saturn's moon Enceladus, as imaged by the Cassini spacecraft in January 2005. The monochrome view is presented along with a color-co...

The terminator between shadow and light cuts across a large crater in the high southern latitudes of the moon Tethys. Also visible near the terminator on the left of the image is a portion of the ...

Across the darkened expanse of Saturn's rings, the Cassini spacecraft spies one of the F-ring shepherd moons. Pandora (84 kilometers, or 52 miles across) orbits Saturn just beyond the outer edges...

A transitional region in Saturn's atmosphere features long, linear cloud shapes, flanked to the north and south by more turbulent swirls. At top center in this view swirls a dark vortex ringed by b...
