Saturn dust

A distant glimpse of Iapetus reveals details within the dark terrain of Cassini Regio, including an impact basin at top that is roughly 400 kilometers (250 miles) wide. Researchers remain unsure a...

Large regions of Saturn's night side are illuminated by the planet's gleaming rings. Except for a sliver of the sunlit crescent at left, this view shows a part of the planet lit almost entirely by ...

This image from NASA's Dawn spacecraft shows numerous grooves (linear depressions) and crater chains, especially in the right hand side of the image of asteroid Vesta.

Inamahari Crater on Ceres, the large well-defined crater at the center of this image from NASA's Dawn spacecraft, is one of the sites where scientists have discovered evidence for organic material.

These color maps of Jupiter were constructed from images taken by the narrow-angle camera onboard NASA's Cassini spacecraft on Dec. 11 and 12, 2000, as the spacecraft neared Jupiter during its flyb...

This anaglyph image shows the topography of the mountain-central complex in asteroid Vesta's south polar region. You need 3D glasses to view this image.

Epimetheus floats above Saturn's swirling skies. Beyond Epimetheus (116 kilometers, or 72 miles across), the narrow F ring appears dark from this vantage point, against the much brighter planet. T...

The vortex at Saturn's north pole -- seen here in the infrared -- takes on the menacing look of something from the imagination of Edgar Allan Poe.

South Polar Cloud Movie October 26, 2004 Full-Res: PIA06124 QuickTime Movie This movie sequence of the south polar region of Titan w...

ORIGINAL CAPTION: At Launch Complex 40 on Cape Canaveral Air Station, workers are installing three Radioisotope Thermoelectric Generators (RTGs) on the Cassini spacecraft. RTGs are lightweight, com...

Lava spills onto the surface of Io during a volcanic eruption.

Craters give a rugged look to surface of Iapetus, especially in the large basin of Engelier visible along the southern limb of the moon in this view. The two-toned surface of the moon is evident i...

In contrast to the image Canyonlands of Titan, this bright terrain is cut by channels that are variable in width; they form both radial and branching networks. Such patterns are reminiscent of ne...

The Cassini spacecraft looks toward the bright linea -- geologically fresh-looking, icy canyons -- on Dione. This view looks toward the trailing hemisphere of Dione (1126 kilometers, or 700 miles ...

This image from NASA's Dawn spacecraft features the distinctive crater Canuleia on the giant asteroid Vesta. Canuleia, about 6 miles (10 kilometers) in diameter, is distinguished by the rays of bri...

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...

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...

A particularly strong jet stream churns through Saturn's northern hemisphere in this false-color view from NASA's Cassini spacecraft. Clouds associated with the jet stream can be seen in the upper...

This image, created using data from NASA's Dawn spacecraft, shows craters (blue markings) called 'cold traps'. These shadowed craters may have been collecting ice for billions of years because they...

This view from NASA's Dawn spacecraft shows a scene from the northern hemisphere of Ceres, north of Occator Crater, which is home of the brightest area on the dwarf planet.

Entering Saturn's Magnetosphere with a Boom July 1, 2004 Full-Res: PIA06347 This graph illustrates the series of sonic booms that...

This artist's concept shows "tides" on Titan raised by Saturn's gravity, as detected by NASA's Cassini spacecraft. Saturn's gravitational pull on Titan, its largest moon, varies as Titan orbits ...

+ QuickTime (no audio, 4.7 MB) The Cassini spacecraft's narrow-angle camera captured Saturn's moon Rhea as it gradually slipped into the planet's shadow – an event known as “ingress” – on Aug. 19,...

This view from NASA's Dawn spacecraft shows the rim of Dantu Crater (78 miles, 125 kilometers wide). This image was taken on June 2, 2016.

Sometimes at Saturn you can see things almost as if from every angle at once, the way a Cubist might imagine things
