These two natural color views taken 11 hours -- one Saturn day -- apart by NASA's Cassini spacecraft help scientists measure wind speeds in the huge storm seen here in the planet's northern hemisph...

This global digital map of Saturn's moon Titan was created using images taken by the Cassini spacecraft's imaging science subsystem (ISS).

This is Cassini's best look yet at the Trojan moon Telesto (24 kilometers, or 15 miles across), which orbits Saturn about 60 degrees ahead of the much larger Tethys (1,071 kilometers, or 665 miles ...

The Cassini spacecraft looks past the illuminated side of Saturn's rings to the brilliant moon Enceladus.

NASA's Dawn spacecraft looked down on Ceres' equatorial region to capture this view of intensely cratered terrain. The image is centered at approximately 3 degrees south latitude, 267 degrees east ...

N00067472.jpg was taken on Oct. 10, 2006 and received on Earth Oct. 10, 2006. The camera was pointing toward TITAN at approximately 189,368 kilometers away, and the image was taken using the CL1 an...

In reality, Janus and the rings both orbit Saturn and are only weakly connected to each other through their mutual gravitational tugs.

A false color look reveals subtle details on Enceladus that are not visible in natural color views. The now-familiar bluish appearance (in false color views) of the southern "tiger stripe" feature...

Interesting geological details on Enceladus can be seen in modest-resolution Cassini spacecraft views like this one. At bottom is the wrinkled and generally crater-free terrain near the moon's sout...

This diagram depicts conditions observed by NASA's Cassini spacecraft during a flyby in Dec. 2013, when Saturn's magnetosphere was highly compressed, exposing Titan to the full force of the solar w...

This view from NASA's Dawn spacecraft shows an unnamed Cerean crater that is surrounded by a smooth blanket of ejecta, including bright material. Both the area around the crater and its floor are p...

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...

The Cassini spacecraft looks toward the limb of Saturn and, on the right of this image, views part of the rings through the planet's atmosphere. Saturn's atmosphere can distort the view of the rin...

This image, made using images taken by NASA's Dawn spacecraft, shows Occator crater on Ceres, home to a collection of intriguing bright spots.

The cold, cratered landscape of Saturn's moon Tethys shines in stark relief in this crescent view. Aside from its obvious aesthetic beauty, this particular Cassini mosaic was obtained mainly to un...

Saturn's rings occupy the foreground of this image. The small moon Janus appears to hover above, while the far larger moon Rhea is partially obscured by the rings. Janus appears to be located dire...

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission.

This is the first global map of the giant asteroid Vesta composed from images recorded by the framing camera aboard NASA's Dawn spacecraft. The equator is running parallel to the upper image border...

An image of Phobos by the High-Resolution Stereo Camera on board ESA's Mars Express spacecraft on January 22, 2007.

Saturn's moon Tethys casts a wide shadow over the planet's F and A rings. Tethys itself is not visible in this image. As Saturn approaches its August 2009 equinox, the planet's moons cast shadows ...

To create the first global, topographic map of Saturn's moon Titan, scientists analyzed data from NASA's Cassini spacecraft and a mathematical process called splining. This method effectively uses ...

Rhea and Enceladus shared the sky just before the smaller moon passed behind its larger, cratered sibling. This image is part of a "mutual event" series in which one moon passes close to or in fro...

This image NASA's Dawn spacecraft shows a fresh scarp rimmed crater on asteroid Vesta with a remarkable distribution of bright and dark material in its interior.
