As Titan Turns

Three large and impressive vortices, including two that appear to be interacting, are captured here as they swirl through Saturn's active southern latitudes. This view shows latitudes slightly to ...

Saturn's moon Tethys turns like a great eye as the enormous crater Odysseus (450 kilometers or 280 miles across) rotates into Cassini's view. Tethys is 1,071 kilometers (665 miles) across. The im...

This monochrome view is the last image taken by the imaging cameras on NASA's Cassini spacecraft. It looks toward the planet's night side, lit by reflected light from the rings, and shows the locat...

This Cassini spacecraft view shows how the bright and dark regions on Iapetus fit together like the seams of a baseball. Some of the material that covers the moon's dark, leading side spills over i...

From on high, the Cassini spacecraft spots a group of faint spokes against the striped landscape of the B ring, the dark region in the middle of the rings here. The spokes appear as irregular blotc...

This sequence of images shows the Sun from its surface to its upper atmosphere and in order of temperature from the first one at 6,000 degrees C on the surface out to about 10 million degrees C.

Saturn's rings are dark and elusive in this view from high above the ringplane, but their shadows on the planet give them away. This view looks toward the unlit side of the rings from about 37 deg...

A pastel crescent of Saturn is interrupted by the moon Mimas and the rings in this color image. Mimas (396 kilometers, or 246 miles across) appears as a dark speck just above the rings. This view ...

Swirling cloud bands, delicate ring shadows and icy moons make the Saturn system a place of supreme natural beauty. Even Cassini's remarkable images can only provide the slightest sense of the expe...

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...

Earth's jet stream is a subject of intense interest and concern thanks to its effects on our weather.

Cassini zooms in, for the first time, on the patchy, bright and dark mountains originally identified in images from the NASA Voyager spacecraft taken more than 25 years earlier. The image was acqui...

    Topography on Titan October 28, 2004 Full-Res: PIA06989   This graph, produced using preliminary altimetry data from Cassini's radar instrument, show...

This wide and sweeping view of the sunlit rings of Saturn takes in the impressive variety in their structure -- from the clumpy and perennially intriguing F ring to the many waves, ringlets and gap...

Saturn poses with Tethys in this Cassini view. The C ring casts thin, string-like shadows on the northern hemisphere. Above that lurks the shadow of the much denser B ring. Cloud bands in the atmo...

The restless winds on gas giant Saturn meet no resistance from any landmass. The boundaries between eastward- and westward-flowing jet streams create turbulent, eddy-filled regions that pump energy...

Dark material splatters the walls and floors of craters in the surreal, frozen wastelands of Iapetus. This image shows terrain in the transition region between the moon's dark leading hemisphere an...

The sequence of seven images in this animation shows sunspots as viewed by NASA's Curiosity Mars rover from June 27 to July 8, 2015. From Mars, the rover was in position to see the opposite side of...

This image of Ceres from NASA's Dawn spacecraft shows a crater near the dwarf planet's equator. The view is centered at approximately 6 degrees south latitude, 230 degrees east longitude.

                  Musical Rings September 27, 2004   Full-Res: PIA06485   Looking something like the fibrous bow of a viol...

Astronaut Edwin E. Aldrin Jr., lunar module pilot, walks on the surface of the moon near a leg of the Lunar Module during the Apollo 11 extravehicular activity (EVA).

This image from NASA's Dawn spacecraft of asteroid Vesta shows chains of craters on an undulating surface probably formed of fine-grained debris, called regolith, which was ejected from large impac...

In this image, obtained by NASA's Dawn spacecraft from above the surface of the giant asteroid Vesta, topography in the area surrounding the south pole area shows impact craters, ridges and grooves...

This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). Jarovit crater, named for the Slavic ...
