Saturn dust

This set of images from NASA's Cassini spacecraft shows cloud patterns in a band around Saturn before a monstrous thunder-and-lightning storm erupted and again after the head of the storm had disap...

This artist's concept shows the rough sizes of the planets relative to each other. Correct distances are not shown. 

The moons Pan (near center) and Daphnis (lower center) cruise through the Encke and Keeler gaps, respectively. The edge waves used to discover Daphnis can be seen here as the brightening on either...

Subtle color differences on Saturn’s moon Mimas are apparent in this false-color view of Herschel Crater captured by NASA's Cassini spacecraft during its closest-ever flyby of that moon. The image...

Tethys' huge Odysseus Crater is brightly lit in the northern latitudes of this Saturnian moon in this Cassini spacecraft view. The crater is seen almost edge-on in the upper left of the image. See...

The Hubble Space Telescope is deployed from the cargo bay of space shuttle Discovery on April 25, 1990 as part of STS-31.

This graphic depicts one possible orbital tour for the Cassini mission. The final four-year tour has yet to be finalized and could look different from this one. The view is from Saturn's north pole...

A view of Titan from the VIMS instrument on the Cassini orbiter. The Huygens probe landed in the small red circle on the boundary of the bright and dark regions. The size of the circle shows the f...

Three of Saturn's satellites are visible in this snapshot from the Cassini spacecraft. Janus (179 kilometers, or 111 miles across) is in the top left of the image.Pandora (81 kilometers, or 50 mil...

Huygens probe jettison, another view April 20, 2004 Highest Resolution Available This artist's rendition shows the Huygens probe a...

Saturn's moon Prometheus casts a narrow shadow on the rings near the much larger shadow cast by the planet in this Cassini spacecraft image taken about five months after Saturn's August 2009 equino...

This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA's Cassini spacecraft on December 29, 2000, during its closest approach to the giant plane...

Saturn's fourth-largest moon, Dione, can be seen through the haze of the planet's largest moon, Titan, in this view of the two posing before the planet and its rings from NASA's Cassini spacecraft....

Working with image data from NASA's Cassini mission, researchers have found evidence that Saturn's moon Enceladus may have tipped over, reorienting itself so that terrain closer to its original equ...

Cassini's prying infrared vision allows details of Saturn's storm-ridden hydrogen atmosphere to be revealed as never before. North of the dark south polar region is what may be a "polygonal wave" ...

This close-up view shows an inner region of Saturn's C ring. It covers a radial location on the rings located approximately 78,000 to 80,500 kilometers (48,500 to 50,000 miles) from the center of t...

The shadowy outlines of the terrain in Vesta's northern region are visible in this image from NASA's Dawn spacecraft. The image comes from the last sequence of images Dawn obtained of the giant ast...

Hints of the curving linear grooves that crisscross bright, icy Enceladus are just discernible in this image captured by the Cassini spacecraft. Enceladus is almost entirely composed of water ice ...

This graphic illustrates Cassini's trajectory, or flight path, during the final two phases of its mission. The 20 Ring-Grazing Orbits are shown in gray; the 22 Grand Finale Orbits are shown in blue...

In this image of the asteroid Vesta, taken by NASA's Dawn spacecraft just shortly before the beginning of high altitude mapping orbit, north is up and the upper right corner is to the northeast.

This composite of 24 images from the Cassini spacecraft shows multiple layers in Titan's stratospheric haze. The most prominent layer is located about 500 kilometers (300 miles) above the surface a...

Saturn and its moon Titan as seen by Pioneer 11 in 1973.

This composite image shows a massive mountain range running just south of Titan's equator. Near the center of the image, the mountain range runs from southeast to northwest. It is about 150 kilomet...

This image, taken on June 25, 2015 by NASA's Dawn spacecraft, shows a portion of the southern hemisphere of dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers), with a resolution ...
