A variety of surface ages is revealed in this 16-image mosaic taken during Cassini's first close flyby of Enceladus, on Feb. 17, 2005. This mosaic shows the trailing hemisphere of Enceladus -- the...
Enceladus: Trailing Hemisphere
This image of the northern polar region of Saturn shows both the aurora and underlying atmosphere, seen at two different wavelengths of infrared light as captured by NASA's Cassini spacecraft.
Saturn's Polar Aurora
+ View Full Res This raw, unprocessed image of Saturn's moon Enceladus was taken on Oct. 19, 2011. As the spacecraft passed Enceladus, its infrared instruments, cameras and other instruments moni...
Enceladus Flyby E-15 (Raw Image #3)
The Cassini spacecraft looks past Saturn's rings and small moon Janus to spy the planet's second largest moon, Rhea. Janus is closest to Cassini here. The rings are between Janus (179 kilometers, ...

This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2012. For more information on raw images check out our Freque...
Mimas and Rings (raw image)
Cassini puts the enormous distances in the Saturn system in perspective with this view of Rhea and Prometheus. Rhea (1,528 kilometers, or 949 miles across) sits in the foreground, while Prometheus...

Befitting moons named for brothers, the moons Prometheus and Epimetheus share a lot in common.
A Forethought and an Afterthought
Bright fractures creep across the surface of icy Dione. This extensive canyon system is centered on a region of terrain that is significantly darker than the rest of the moon. Part of the darker te...

A bright ray crater dominates this view of the leading hemisphere of Rhea, obtained at a time when the Sun was nearly aligned behind the Cassini spacecraft, or "opposition." At opposition, shadows...
The Cassini spacecraft's close flyby of Epimetheus in December 2007 returned detailed images of the moon's south polar region. The view shows what might be the remains of a large impact crater co...
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...
Haze Layers on Titan
These three views of Titan from the Cassini spacecraft illustrate how different the same place can look in different wavelengths of light. Cassini's cameras have numerous filters that reveal featur...
Cassini's Views of Titan
As seen in this Landsat 8 image, several glaciers flow into the Shimshal Valley perpendicular to the flow of the river, and they have little room to move before they intersect with the water.
When Glaciers and Rivers Collide
This image from NASA's Dawn spacecraft shows large craters Urvara (top) and Yalode (bottom) on dwarf planet Ceres. The two giant craters were formed at different times. Urvara is about 120-140 mill...

Saturn's A ring displays a marked asymmetry in brightness between the region nearer to the Cassini spacecraft and the region farther from it. The A ring is the broad, bright section of the rings ou...
Difference on the Dark Side
The Cassini spacecraft spies Enceladus and Epimetheus near the limb of Saturn. Geologically active Enceladus is 505 kilometers (314 miles) across; smaller, more irregularly shaped Epimetheus is 11...

Saturn's Hot Plasma Explosions
Far above the howling winds of Saturn, its icy moons circle the planet in silence. Mimas is seen near the upper right, while Tethys hovers at the bottom. Dark shadows cast by the see-through rings ...
A pair of small moons join Saturn's second largest moon in this Cassini spacecraft image spotlighting Rhea in front of the rings. Rhea (1,528 kilometers, or 949 miles across) is in the center fore...
