The ghostly spokes in Saturn's B ring continue to put on a show for the Cassini spacecraft cameras in this recent image. The spokes, believed to be a seasonal phenomenon, are expected to disappear ...
Still Active Spokes
Prometheus shows up bright in this image of the dark side of the rings. The bright band that appears above Prometheus in this image is the Cassini division separating the (very dark) B ring and th...

Saturn sits nested in its rings of ice as Cassini once again plunges toward the graceful giant.
On the Final Frontier
The Cassini spacecraft captures a far-off view of the two-toned surface of Saturn's moon Iapetus. Scientists continue to investigate the nature of this moon's surface. See The Other Side of Iapetu...
This image of Ceres, taken by NASA's Dawn spacecraft, shows Sintana Crater (36 miles, 58 kilometers wide) at top, just right of center. The rim of a large crater called Zadeni (80 miles, 128 kilome...

Prometheus is caught here casting a shadow on the F ring. To the right, the F ring also shows a gore where Prometheus recently entered into the ring, scattering material out of its way. The image...
Shadows and Gores
The Cassini spacecraft observes the wrinkled surface of Enceladus. The geologically active south polar region is visible at bottom. This view looks toward the Saturn-facing side of Enceladus (504 ...
For more than 22 years, since before Cassini even launched, summer interns helped the mission happen. But with the spacecraft's journey ending in September, the current summer interns will be Cassi...

TThis image was taken during Cassini's third close approach to Titan on Feb. 15, 2005. The image was taken with the Cassini spacecraft narrow angle camera through a filter sensitive to wavelengths...
Close Titan Flyby 3, Image #3
Vertical structures created by Saturn's small moon Daphnis cast long shadows across the rings in this dramatic image taken as the planet approaches its mid-August 2009 equinox. Daphnis, 8 kilomete...
On May 28, the Cassini spacecraft will fly by Saturn's moon Titan in its last flyby of the original four-year tour, but Cassini’s exploration of Saturn will continue for two more years. This flyby ...
Cassini Flies By Titan, Readies for Extended Tour
The Cassini spacecraft surveys the battered surface of icy Tethys. The great impact basin straddling the terminator is itself overprinted by many smaller impact sites. The view in this image is to...
