Merging Saturnian Storms
The first Kuiper Belt Object -- 1992 QB1 -- was discovered in 1992 by American astronomers David Jewitt and Janet Luu using the 2.2-m telescope at Mauna Kea in Hawaii.
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 23, 2015, and has a resolution o...

+ View annotated version This set of images from NASA's Cassini mission shows the evolution of a massive thunder-and-lightning storm that circled all the way around Saturn and fizzled when it ran ...
Storm Head, Meet Tail
The sharp change in brightness that runs diagonally across the center of this image represents the boundary between Saturn's C and B rings. This location sits at about 92,000 kilometers (57,200 mi...
On the Border
From just below the plane of Saturn's rings, the Cassini spacecraft looks at the rings edge-on and sees the planet's second largest moon beyond. Although Rhea may appear to be in the foreground of...
Rhea and Edge-On Rings
A scan across Saturn's incredible halo of ice rings yields a study in precision and order. This natural color mosaic was acquired by the Cassini spacecraft as it soared 39 degrees above the unillu...
Expanse of Ice
Gaseous Saturn rotates quickly -- once every approximately 10.8 hours -- and its horizontal cloud bands rotate at different rates relative to each other.
The Cassini spacecraft awaits placement of its payload fairing at Launch Pad 40 at Cape Canaveral Air Station (CCAS) to protect Cassini during launch.
Weeks Before Launch
During two close flybys of Saturn’s moon Enceladus in 2008, the cameras on NASA's Cassini acquired several very high-resolution images of specific regions of the south polar terrain. These images h...
Gazing across the plains of Saturn's icy rings, Cassini catches the F ring shepherd moon Pandora hovering in the distance. See Pandora's Color Close-up for an up-close color view of Pandora (84 ki...
The Cassini spacecraft snapped this exquisite, close-up view of Saturn's moon Janus, looking toward the south polar region, on Feb. 20, 2008. Janus is 181 kilometers (113 miles) across. The image...
Janus: Down South
Saturn's moon Dione passes in front of the larger moon Titan, as seen from the Cassini spacecraft.

This global digital map of Saturn's moon Rhea was created using data obtained by NASA's Cassini and Voyager spacecraft. The map is an equidistant projection and has a scale of 417 meters (1,400 fe...
Map of Rhea - November 2009
Until recently, Saturn's tiny moon Enceladus was thought to be cold and dead. But close observations by the Cassini spacecraft have revealed dramatic features and made this frozen world a new targe...
Saturn Moons Explorer -- Enceladus
The dark shadows that drape Saturn's northern latitudes are split by three familiar bright gaps. From bottom to top, sunlight passes through the broad Cassini Division (4,800 kilometers, or 2,980 m...
Sun Through the Shadows
This close-up view of the icy surface of Europa, a moon of Jupiter, was obtained on December 20, 1996, by the Solid State Imaging system on board the Galileo spacecraft during its fourth orbit arou...
Close-up of Europa's Surface
The moon Iapetus, like the "force" in Star Wars, has both a light side and a dark side.
Path to the Dark Side
This temperature map of Saturn's moon Iapetus is constructed from observations of Iapetus's infrared heat radiation taken with the Cassini composite infrared spectrometer instrument during the Dec....

This image of Earth from lunar orbit was acquired by the NASA 's Moon Mineralogy Mapper - a guest instrument onboard the Indian Space Research Organization's Chandrayaan-1 mission to the moon. Aust...
Moon Mapper Looks Homeward
NASA's Dawn spacecraft obtained this image of a young and old crater at the night and day boundary on asteroid Vesta. The image has a resolution of about 260 meters per pixel.
