Resembling ornaments hanging from Saturn's rings, two moons accent this portrait of the planet. The moon Enceladus (504 kilometers, or 313 miles across) is on the right. Dione (1,123 kilometers, o...
The broad morphology of asteroid Vesta's mountain/central complex is clear in this image from NASA's Dawn spacecraft; it is a roughly circular topographic mound, which is approximately 200km in dia...

Epimetheus is a lonely dot beyond Saturn's rings. The little moon appears at lower left, outside the narrow F ring. Several very faint spokes lurk in the B ring, at right. This view looks toward ...
Epimetheus and the Dark Side
The Cassini spacecraft catches a glimpse of the bright fractures that adorn the trailing side of icy Dione. North on Dione (1,126 kilometers, or 700 miles across) is up. The image was taken in ...
Dione's Fractured Face
The ringed planet wears a broad grin in this image from Cassini, as the icy rings cast long, sweeping shadows across the northern hemisphere. Fantastic details are visible in the bright and dark of...
The Cassini spacecraft carried the European Space Agency's Huygens probe to Saturn and released it in December 2004. The probe landed on Titan Jan. 14, 2005, acquiring a set of images using the de...

This image is from Cassini's final observation of Saturn's icy moon Rhea on May 2, 2017. The spacecraft was at the time high above the plane of Saturn's rings, looking down at Rhea's northern hemis...
Janus, Saturn's small moon named after the two-faced god, here displays two illuminated hemispheres. Janus (179 kilometers, or 111 miles across) orbits beyond the thin F ring in the top left of th...
This movie created from images obtained by NASA’s Cassini spacecraft shows a propeller-shaped structure created by a hidden, embedded moon moving through one of Saturn's rings. The moon, likely ab...

Saturn's moon Prometheus chases Pandora in this Cassini view, but the outcome of their race has already been decided by gravity. Prometheus orbits closer to Saturn and thus moves faster than does P...
Saturn's moon Daphnis creates waves of disturbance in the Keeler Gap in this image of the wide A ring and narrow F ring. Daphnis (8 kilometers, or 5 miles across) is a small point of light in the ...
