Sometimes at Saturn you can see things almost as if from every angle at once, the way a Cubist might imagine things
Saturn's two ring-embedded moons are pictured here, along with clearly visible signs of their perturbing effects on the ring edges that border the gaps they inhabit. These ripples along the ring e...

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...
Map of Hydrated Minerals on Vesta
This mosaic of 15 Cassini images of Saturn's F ring shows how the moon Prometheus creates a gore in the ring once every 14.7 hours, as it approaches and recedes from the F ring on its eccentric orb...
The Prometheus Effect
+ View Full Res This image was taken by NASA's Cassini spacecraft on April 14, 2012. The camera was pointing toward Enceladus at approximately 115 miles (185 kilometers) away. This image has not...
Enceladus Terrain (Raw image)
This Cassini image shows the cratered surface of Saturn's moon Rhea, with impact craters near the terminator thrown into sharp relief. Rhea is Saturn's second-largest moon, at 1,528 kilometers (9...
These images from NASA's Dawn spacecraft are located in asteroid Vesta's Sextilia quadrangle, in Vesta's southern hemisphere.
Apparent Brightness and Topography Images of Helena and Laelia Craters
The light of a new day on Saturn illuminates the planet’s wavy cloud patterns and the smooth arcs of the vast rings.
Dawn's Early Light
This collage showcases several of Saturn's moons. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Labora...
Several of Saturn's moons
Saturn's moon Prometheus, seen here looking suspiciously blade-like, is captured near some of its sculpting in the F ring.
Saturn’s C ring isn’t uniformly bright. Instead, about a dozen regions of the ring stand out as noticeably brighter than the rest of the ring, while about half a dozen regions are devoid of ring ma...

The Cassini spacecraft takes one of its last good looks at Iapetus, a Saturnian moon known for its yin-yang-like, bright-and-dark color pattern. This view looks toward the south pole of Iapetus (1...
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...
Tracking Sunspots from Mars, Summer 2015
It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 miles (45,000 kilometers) away from the rings.
The Cassini spacecraft gazes into the blustery, ever changing atmosphere of Saturn as the tiny shadow of Epimetheus drifts across the cloud tops. The view looks toward a region in Saturn's atmosph...

Cassini Flies By Earth
Cassini captured this arresting view of Saturn just before Epimetheus crossed into the blinding glare of the planet's sunlit crescent and was lost. As it orbits Saturn, Epimetheus (116 kilometers,...
A Captivating Vision
The Cassini spacecraft captured this image of a dimly lit Titan as Saturn's largest moon was eclipsed by the planet. This view looks up toward the south pole of Titan which lies on the terminator ...
Titan in Eclipse
The Cassini spacecraft continues to investigate the intriguing structure in Saturn's outer B-ring edge. This region has a much perturbed character compared to the orderly rings around it. Ring sci...
This high-resolution view shows, at left, a spiral density wave in Saturn's inner B ring. A spiral density wave is a spiral-shaped massing of particles that tightly winds many times around the plan...
These images from NASA's Dawn spacecraft show part of the rim of asteroid Vesta's south polar basin, which is dominated by a large scarp (cliff) that runs vertically across the center of the images.
Topography of a Scarp and Hummocky Terrain
The Cassini spacecraft spies a ''fan'' in Saturn's tenuous F ring. This fan-like structure appears as dark lines spreading outward from the left of the bright clump of ring material near the cente...
This map illustrates the planned imaging coverage for the Descent Imager/Spectral Radiometer, onboard the European Space Agency's Huygens probe during the probe's descent toward Titan's surface on ...
