Image of Saturn
This image of fractures across Occator Crater's floor on Ceres was obtained by NASA's Dawn spacecraft on July 4, 2018 from an altitude of about 30 miles (48 kilometers).
Fractures Across Occator Crater's Floor
In this extremely narrow angle field-of-view artist's rendering Iapetus, with its notable dark surface, occupies the foreground with a dimly lit crescent Saturn low in the sky. Iapetus' surface sh...
Iapetus' Dark Surface
Cassini looks upward at the south polar region on Rhea during a recent distant encounter. Rhea's icy surface is so heavily saturated with impact craters that the moon's limb, or edge, has a rugged,...
Above Rhea's South Pole
This unique movie, showing Saturn's rotation in three different spectral filters, demonstrates Cassini's ability to probe various levels within the planet's outer cloud layers. From left to right,...
Three Views of Saturn
Sometimes at Saturn you can see things almost as if from every angle at once, the way a Cubist might imagine things
Saturn's tiny moon Pan orbits in the middle of the Encke Gap of the planet's A ring in this image from the Cassini spacecraft. Pan (17 miles, or 28 kilometers across) is visible as a bright dot in...

Saturn Through the Blue Filter
Saturn's moon Enceladus, seen beyond the outline of the planet's night side, spews water ice from its south polar region. Enceladus is farther from Cassini than the planet is here. The plumes can ...
Activity Past Dark Side
The transition region from Saturn's moon Iapetus' dark leading hemisphere to its bright trailing hemisphere is a complicated patchwork of craters and highlands, with low elevations filled in by dar...

Cassini Approaches Saturn
Saturn's moon Daphnis casts a short shadow on the A ring in this image taken about six months after the planet's August 2009 equinox. Daphnis (8 kilometers, or 5 miles across) appears as a tiny br...

Galileo Galilei's observations that Venus appeared in phases -- similar to those of Earth's Moon -- in our sky was evidence that Venus orbited the sun and contributed to the downfall of the centuri...

Eyeing the Culprit
The shadow of Saturn's moon Mimas dips onto the planet's rings and straddles the Cassini Division in this natural color image taken as Saturn approaches its August 2009 equinox. The novel illumina...
Across Resplendent Rings
This map from NASA's Dawn mission indicates the presence of hydrated minerals on the giant asteroid Vesta about 30 degrees north latitude, in August 2011. At the time, it was winter in Vesta's nort...

This view from NASA's Dawn spacecraft shows the rim of the large impact feature named Yalode in the southern mid-latitudes on dwarf planet Ceres. Linear, roughly parallel features are visible in th...
Dawn HAMO Image 68
Clouds swirl about in Saturn's active atmosphere. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 29, 2008 at a distance of approximately 1.278 million...
Dione appears small and far off in this Cassini view, which nonetheless manages to capture a detailed look at the moon's beautiful bright streaks, or "linea." The linea are a system of braided cany...
Dione's Good Side
Two large craters lie along the boundary between day and night on Saturn's moon Rhea. The bright spots in the middle of each crater may be prominent central peaks. Rhea is 1,528 kilometers (949 mi...
Swathed in its thick blanket of atmosphere, frigid Titan approaches the brilliant limb of Saturn. This view was obtained just minutes after the wide-angle view, Titan Slips Away . Images taken u...
Titan Approaches Saturn
Saturn's moon Dione hangs in front of Saturn's rings in this view taken by NASA's Cassini spacecraft during the inbound leg of its last close flyby of the icy moon.
Dione: Craters and Rings
Cassini conducts a successful close flyby of Saturn's icy moon Enceladus (en-SELL-uh-duss) at 500 kilometers (310 miles) from its surface today. Enceladus is the coldest of the Saturnian moons and ...
This map of Titan's surface illustrates the regions that will be imaged by Cassini during the spacecraft's close flyby of the smog-enshrouded moon on April 16, 2005. At closest approach, the spac...
Cassini's April 16 Flyby of Titan
On the top right of this Cassini spacecraft image, Saturn's moon Dione may appear closer to the spacecraft because it is larger than the moon Enceladus in the lower left. However, Enceladus was act...
