Atmospheric Motion

This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on August 21, 2015, and has a resolution o...

Saturn's rings cut across this view of the planet's largest moon, Titan. Dark albedo features on Titan (5,150 kilometers, or 3,200 miles across) and the moon's north polar hood are visible here. S...

The "H"-shaped region Fensal-Aztlan is faintly visible on Saturn's murky moon Titan in this enhanced clear-filter view from Cassini. While most of the light passing through the clear filters is vi...

With the Sun directly behind Cassini, the spacecraft spies the opposition surge in Saturn's inner A ring. The opposition effect becomes visible from this special viewing geometry. See Opposition S...

The far left image shows the bright-dark boundary region on Saturn's moon Iapetus at far-ultraviolet wavelengths, viewed by Cassini's ultraviolet imaging spectrograph on Sept. 10, 2007. These wa...

The brightly reflective moon Enceladus appears before Saturn's rings while the larger moon Titan looms in the distance. Jets of water ice and vapor emanating from the south pole of Enceladus (hint...

Like a giant eye for the giant planet, Saturn's great vortex at its north pole appears to stare back at Cassini as Cassini stares at it.

This image is one frame from a movie clip of cloud motions on Jupiter, from the side of the planet opposite to the Great Red Spot. It was taken in the first week of October 2000 by the narrow-angle...

This global digital map of Saturn's moon Iapetus was created using data taken during Cassini and Voyager spacecraft flybys. The map is an equidistant projection and has a scale of 641 meters (2,103...

The Cassini spacecraft looks past the cratered south polar area of Saturn's moon Rhea to spy the moon Dione and the planet's rings in the distance. Dione's "wispy" terrain can be seen on the trail...

+ Read Feature NASA's Cassini spacecraft took this raw, unprocessed image of Saturn's moon Rhea on March 10, 2012. The camera was pointing toward Rhea at approximately 26,157 miles (42,096 kilomet...

This Cassini narrow-angle camera image -- one of those acquired in the survey conducted by the Cassini imaging science team of the geyser basin at the south pole of Enceladus -- was taken as Cassin...

Astronomers have long known that Saturn's rings reflect sunlight most strongly when Earth is located directly between Saturn and the sun. Flat, shiny surfaces (like a mirror or a pond) can appear p...

Unlike most of the dull grey moons in the Solar System, Hyperion's color is a rosy tan, as this view shows. The origin of the moon's unusual hue is not known. Some scientists suspect the color com...

The shepherding moon Pandora, near the bottom of the image, casts a shadow on Saturn's thin F ring as the planet nears its August 2009 equinox. Pandora (81 kilometers, or 50 miles across) orbits o...

High-Altitude Clouds

This high-resolution geological map of Vesta is derived from NASA's Dawn spacecraft data.

Artist's rendering of NASA's Cassini spacecraft observing a sunset through Titan's hazy atmosphere.

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Tuccia quadrangle, in Vesta's southern hemisphere.

This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013.

Asteroid 2015 TB145 is depicted in eight individual radar images collected on Oct. 31, 2015 between 5:55 a.m. PDT (8:55 a.m. EDT) and 6:08 a.m. PDT (9:08 a.m. EDT).

Saturn's moon Mimas, whose low density suggests that it is primarily composed of ice, has a flattened or oblate shape reminiscent of Saturn's (see Saturn in Color ). The moon's equatorial dimension...

Wind-blown clouds and haze high in Saturn's atmosphere are captured in a movie made from images taken by the Cassini narrow angle camera between Feb. 15 and Feb. 19, 2004.

+ Unnnotated Version This mosaic shows an updated global map of Saturn's icy moon Enceladus, created using images taken during Cassini spacecraft flybys. The map incorporates new images taken du...

In this magnificent view, delicate haze layers high in the atmosphere encircle the oblate figure of Saturn. A special combination of spectral filters used for this image makes the high haze become ...
