Mimas is caught in the spotlight beneath Saturn's rings in this amazing view from Cassini. Notable is the brightened outermost edge of the A ring beyond the narrow Keeler gap and the periodic brigh...

Cassini looks up from beneath the ringplane to spot Prometheus and Atlas orbiting between Saturn's A and F rings. Prometheus is 102 kilometers (63 miles) across. Atlas is 20 kilometers (12 mile...

Wispy fingers of bright, icy material reach tens of thousands of kilometers outward from Saturn's moon Enceladus into the E ring, while the moon's active south polar jets continue to fire away. Th...

The surface of Ceres is covered with craters of many shapes and sizes, as seen in this frame from an animation of a map of the dwarf planet's surface as seen by NASA's Dawn spacecraft on Feb. 19, 2...

Cassini's high-gain antenna is able to operate at S, X, Ka, and Ku-band frequencies. In addition to communications (X-band between Earth and orbiter, and S-band from probe to orbiter), radio scie...

NASA's Cassini spacecraft successfully completed its Oct. 1 flyby of Saturn's moon Enceladus, capturing these raw, unprocessed images of the moon and its dramatic plumes of water vapor and ice. Th...

Complex and unique canyon systems appear to have been intricately carved into older terrain by the ample flow of liquid methane rivers on Saturn's moon Titan, as seen in this radar image taken by N...

These images, derived from data obtained by NASA’s Galileo spacecraft, show the subtle ripples in the ring of Jupiter that scientists have been able to trace back to the impact of comet Shoemaker-L...

NASA's Dawn spacecraft obtained this view of shadowed craters near Ceres' north pole at a distance of about 240 miles (385 kilometers) above the surface on May 28, 2016.

This false-color infrared image, obtained by NASA's Cassini spacecraft, shows clouds of large ammonia ice particles dredged up by a powerful storm in Saturn's northern hemisphere. Large updrafts dr...

The change in Titan's haze layer is illustrated in this figure, derived from data obtained by NASA's Cassini spacecraft. The picture of Titan in panel a was taken on May 3, 2006, while the picture...

On a clear day on Mars, you can see tens of thousands of rocks.

These two Cassini images taken 23 minutes apart show many vortices and turbulent wakes in Saturn's atmosphere. They also show the overall filamentary structure of the flow in the atmosphere. Many ...

Each of these two montages shows four synthetic views of Titan created using data acquired by the visual and infrared mapping spectrometer (VIMS) on board NASA's Cassini spacecraft between 2004 and...

Two images of Saturn's A and B ring showcase the opposition effect, a brightness surge that is visible on Saturn's rings when the Sun is directly behind the spacecraft. This view is of the B ring....

This 3D image was obtained as Dawn approached Vesta and circled the giant asteroid during the mission's survey orbit phase. You need 3D glasses to view this image.

These side-by-side views of a star seen through Saturn's densely populated B ring show marked contrast between the region where spokes -- the ghostly radial features periodically seen in the B ring...

This raw image obtained by NASA's Cassini spacecraft of Saturn's moon Rhea shows an old, cratered surface seen with a low sun angle, casting deep shadows on the crater floors. Cassini's wide-angle ...

The Cassini orbiter continues its observations of Saturn¿s mysterious moon Titan, stealing another early peek at the haze-enshrouded surface. Cassini's view of Titan now surpasses Earth-based obser...

+ Video Launch Page On March 12, NASA's Cassini spacecraft will make its closest flyby yet to Saturn's moon Enceladus. Cassini's goal: To scoop up samples of water-ice particles and gas spewing fr...

Wispy terrain reflects sunlight brightly in the lower left of this Cassini image of the northern latitudes of Saturn's moon Dione. These "wisps" are actually fractures on the trailing hemisphere of...

Saturn's moon Mimas appears near Saturn, dwarfed by its parent planet in this image. Mimas (246 miles, or 396 kilometers across) appears tiny compared to the storms clearly visible in far northern...

A huge, handle-shaped prominence erupting from the Sun in 1999.

In addition to being evidence of past impacts, craters can serve another valuable scientific purpose.
