Saturn dust

What looks like a pair of Saturnian satellites is actually a trio upon close inspection.

This image taken by NASA's Mars Reconnaissance Orbiter shows the very steep outer scarp of north polar layered deposits on Mars. Every year there is a lot of slope activity in the springtime when s...

In this movie from NASA's Cassini spacecraft, the gravitational pull of Saturn's moon Prometheus creates patterns in Saturn's F ring. This movie also happens to show a small trail of icy ring parti...

The Cassini spacecraft looks toward the battered surface of the moon Rhea. See Ancient Plains of Rhea and Bright Rays to learn more about this moon. This view looks toward leading hemisphere of Rh...

The objectives of the Cassini mission can be divided into five scientific categories. Titan, at the upper right, is the target for the Huygens probe, which will descend to the surface of Saturn's...

Workers secure the attachments of NASA's Dawn spacecraft onto the upper stage booster.

NASA's Dawn spacecraft shows the central area of the south polar basin. This view is rotated by approximately 90°.

Saturn looms in the foreground of this mosaic of Cassini images, taken by the spacecraft on May 28, 2017. The planet is adorned by ring shadows. The icy rings emerge from behind the planet.

This is a raw, or unprocessed, image taken by the Cassini spacecraft during its close flyby of Saturn's moon Iapetus on Sept. 10, 2007.

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...

Having passed closer to Tethys than the Voyager 2 spacecraft, Cassini has returned the best-ever natural color view of this icy Saturnian moon. As seen here, the battered surface of Tethys (1,060 ...

This graphic shows the geologic time scale of asteroid Vesta derived from geologic mapping.

Dione's leading hemisphere appears relatively smooth and placid here, compared to the fractured landscape on its trailing hemisphere. See Incredible Cliffs for a view of the trailing hemisphere. ...

Saturn’s rings are perhaps the most recognized feature of any world in our solar system. Cassini spent more than a decade examining them more closely than any spacecraft before it.

This image shows rough ice in the southern part of Saturn’s moon Enceladus. It was created using synthetic-aperture radar (SAR) data acquired by NASA’s Cassini spacecraft on Nov. 6, 2011. The SAR i...

“This is a view of crescent Saturn, based on the raw image from Cassini on March 12, 2014."

A mosaic of two images of Saturn's moon Phoebe taken shortly after Cassini's flyby on June 11, 2004, gives a close-up view of a region near its South Pole. The view, taken about 13,000 kilometers (...

This image of Ceres' Occator Crater's eastern rim was obtained by NASA's Dawn spacecraft on June 9, 2018 from an altitude of about 30 miles (48 kilometers).

NASA's Dawn spacecraft captured this view on May 28, 2016, showing a relatively young crater with smooth walls and a sharp rim. The crater has a prominent central ridge, imprinted upon the rim of t...

Bright and dark terrains on Titan's trailing hemisphere are revealed by Cassini's Imaging Science Subsystem in this mosaic of images taken during the T28 flyby in April 2007. The region shown in t...

Large areas of this Cassini synthetic aperture radar image of Titan are covered by long, dark ridges. They resemble the "cat scratches" seen in other places on Titan, but here they are longer and ...

This plot shows the variation in brightness of the plume of material, composed of all the geysers erupting from the south polar terrain of Saturn's moon Enceladus, as a function of the moon's orbit...
