Saturn's high north is a seething cauldron of activity filled with roiling cloud bands and swirling vortices. A corner of the North Polar Hexagon is seen at upper left. This view looks toward a re...

This image of Occator Crater on Ceres limb -- short exposure -- was obtained by NASAs Dawn spacecraft on August 14, 2018 from an altitude of about 1149 miles (1849 kilometers).

Ever-changing kinks and wiggles define Saturn's dynamic F ring. The evolution of F-ring features like those seen here are of interest to ring scientists because they reveal a great deal about the p...

This 3-D image, or anaglyph, shows the center of Occator Crater, the brightest area on dwarf planet Ceres, using data from NASA's Dawn mission. The bright central area, including a dome that is 0.2...

This group of spokes in Saturn's B ring extends over more than 5,000 kilometers (3,100 miles) radially across the ringplane. The bright wedge to the left of center has a trailing edge (its top rig...

Bright spokes and the shadow of a moon grace Saturn's B ring in this Cassini spacecraft image.

This Cassini image is one of the highest-resolution views ever taken of Saturn's moon Pandora, a moon that orbits just outside the narrow F ring.

The extreme contrast in this view of the unlit side of Saturn's rings is intentional. Contrast-enhanced views like this are used to look for spokes (the transient, ghostly lanes of dust seen in NAS...

This image shows the warmest places in the south polar region of Saturn's moon Enceladus. The unexpected temperatures were discovered by Cassini's composite infrared spectrometer during a close fl...

Dark Desolation June 14, 2004 Full-Res: PIA06069 On June 11, 2004, during its closest approach to Phoebe, Cassini obtained this ex...

The Cassini spacecraft gazes toward a distant star as Saturn's rings slip past in the foreground. At upper left is the outer A ring, with its dark Keeler Gap. At lower right, a train of bright clum...

There is much to examine in detailed close-ups like this one of Saturn's atmosphere. Scientists are particularly interested in the bright, and in some places turbulent-looking, thin boundary betwe...

This is a narrow angle field-of-view artist's rendering from the bottom of a large ice crevasse on the surface of Phoebe, the least known of all the Saturnian satellites. Since Cassini will never ...

A serene orb of ice is set against the gentle pastel clouds of giant Saturn. Rhea transits the face of the gas giant, whose darkened rings and their planet-hugging shadows appear near upper right. ...

A bizarre six-sided feature encircling the north pole of Saturn near 78 degrees north latitude has been spied by the visual and infrared mapping spectrometer on NASA's Cassini spacecraft. 

The Cassini spacecraft's Titan Radar Mapper instrument imaged this area atop Xanadu, the bright area of Titan, on April 30, 2006. The picture is roughly 150 kilometers (93 miles) wide by 400 kilome...

Aerial view of Meteor Crater in Arizona.

Scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years.

This view from NASA's Dawn spacecraft captured on Dec. 21, 2015 shows a portion of the northern hemisphere of Ceres. Bright material can be seen in the wall of the large crater at upper right.

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Urbinia quadrangle, in Vesta's southern hemisphere.

A meteor captured during the height of the Perseid shower in August 2018.

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...

The craters Takel and Cozobi are featured in this image of Ceres from NASA's Dawn spacecraft. Takel is the young crater with bright material on the left of this image, and Cozobi is the sharply def...

The flattened, potato-like form of Prometheus glides silently within the Roche Division, between Saturn's A and F rings. Prometheus (86 kilometers, or 53 miles across at its widest point) is on th...

Images taken with Cassini's ultraviolet imaging spectrograph shed some light on the dark side of Saturn's moon Iapetus. Scientists are trying to figure out what painted Iapetus' dark side. This is ...
