Great Dark Spot

The ancient and battered surface of Saturn's moon Rhea shows a notable dark swath of territory near the eastern limb in this image from Cassini. This view shows principally the Saturn-facing hemi...

A large, bright and complex convective storm that appeared in Saturn's southern hemisphere in mid-September 2004 was the key in solving a long-standing mystery about the ringed planet. Saturn's at...

Saturn's north pole retains its bluish hue in this true color Cassini image, even as northern winter is coming to an end. The azure blue of Saturn's winter hemisphere during the early Cassini prim...

Tiny Epimetheus is dwarfed by adjacent slivers of the A and F rings. But is it really? Looks can be deceiving!

The brilliant supergiant star, Rigel, emerges from behind the haze of Saturn's upper atmosphere in this Cassini view. Rigel is one of the 10 brightest stars in Earth's sky and forms the left foot ...

Saturn's moon Telesto is visible below and to the left of center in this image from the Cassini spacecraft. Telesto (24 kilometers, or 15 miles across) shares the orbit of Saturn's moon Tethys (...

Recent images of features in Saturn's C ring called "plateaus" reveal a streaky texture that is very different from the textures of the regions around them. 

A couple of Saturn's moons orbit beyond four of the planet's rings in this image. Starting from the top right of the picture are the C ring, B ring, A ring, thin F ring, the small moon Pandora (81...

This new, detailed global mosaic color map of Pluto is based on a series of three color filter images obtained by the Ralph/Multispectral Visual Imaging Camera aboard New Horizons during the NASA s...

Mariner 9's view of the "labyrinth" at the western end of Vallis Marineris on Mars. 

As it entered the Saturn system, NASA's Cassini spacecraft performed its first targeted flyby of one of the planet's moons.

Detecting Lightning From Saturn August 5, 2004 Full-Res: PIA06414 This artist concept shows how Cassini is able to detect radio si...

Saturn’s moon Dione drifts before the planet’s rings, seen here almost edge on.

This poetic wide-angle camera view of Saturn reveals several small, dark storms in the southern latitudes, where storm activity has been prevalent since before Cassini arrived in orbit. Also notab...

Southern Storms and Streaks September 15, 2004 Full-Res: PIA06482 Saturn's southern polar region is haunted by a number of dark storm...

                  Plateaus and Gaps December 13, 2004   Full-Res: PIA06540   This fantastic close-up of Saturn's outer C r...

The Cassini spacecraft snapped this Saturn portrait from the distance of Iapetus, just before beginning its close encounter with the two-toned moon. Rhea (1,528 kilometers, or 949 miles across) is...

Occator Crater and Ahuna Mons appear together in this view obtained by NASA's Dawn spacecraft on February 11, 2017.

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...

                  Saturn's Sunlit Rings July 1, 2004     After becoming the first spacecraft to enter Saturn's orbit,...

This colorized mosaic from NASA's Cassini mission shows the most complete view yet of Titan's northern land of lakes and seas. Saturn's moon Titan is the only world in our solar system other than E...

Both luminous and translucent, the C ring sweeps out of the darkness of Saturn's shadow and obscures the planet at lower left. The ring is characterized by broad, isolated bright areas, or "plateau...

This image of Oppia AV-L-22, 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.

The ring moon Prometheus continues its work shaping the delicate F ring as Dione looks on. It is easy to see how Prometheus has an irregular, oblong shape, while Dione is quite round. The rings ar...

“I processed two images captured by Cassini on March 21, 2006 to create an anaglyph [a stereoscopic image that requires 3-D glasses to see]."
