Saturn's tiny moon Pan orbits in the middle of the Encke Gap of the planet's A ring in this image from the Cassini spacecraft. Pan (17 miles, or 28 kilometers across) is visible as a bright dot in...
Pan In the Middle
With Enceladus nearly in front of the Sun from Cassini's viewpoint, its icy jets become clearly visible against the background. The view here is roughly perpendicular to the direction of the linea...

The Cassini spacecraft acquired this view of Rhea's leading hemisphere near "opposition," or with the Sun almost directly behind the camera. Under this geometry, topography appears less rugged be...
Where Have All the Shadows Gone?
This Cassini narrow-angle camera image -- one of those acquired in the survey conducted by the Cassini imaging science team of the geyser basin at the south pole of Enceladus -- was taken as Cassin...
The Cassini spacecraft watches as clouds swirl through Saturn's equatorial latitudes. The two transitions between the light and dark areas seen here north and south of the ringplane are each locat...
This image from NASA's Dawn spacecraft shows craters with both sharp and smooth crater rims in asteroid Vesta's southern hemisphere. Detailed structure is seen more readily in the image with a smal...
Unusual Craters on Vesta III
Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true color view. The long, dark lines on the atmosphere are shadows cast by the planet's rings. Sa...

This figure shows a possible history of the south polar terrain on Saturn’s moon Enceladus. The top figure is a digital map that shows the four major "tiger stripe" fractures and the ropey terrai...
Ancient Terrain on Enceladus
This image of Saturn's moon Enceladus shows a region of craters softened by time and torn apart by tectonic stresses. Fractures 100 to 400 meters (330 to 1,300 feet) in width crosscut the terrain: ...
This very deep combined image shows the interstellar asteroid ‘Oumuamua at the center of the image.

The Moon sets over the early morning desert in Arches National Park, Utah on July 28, 2018.
During its final close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft captured this view featuring the nearly parallel furrows and ridges of the feature named Samarkand Sulci.

This image from NASA's Dawn spacecraft of asteroid Vesta shows Octavia crater, located in Vesta's Marcia quadrangle, just south of Vesta's equator. Octavia's rim is fresher on the right side and mo...
Two companion moons share the sky before the Cassini spacecraft. Tethys is seen here with one of its two Trojan moons. Calypso, which trails the larger moon in its orbit by 60 degrees, is a couple ...
Tethys and Calypso
This image from NASA's Cassini mission shows a region in Saturn's A ring. The level of detail is twice as high as this part of the rings has ever been seen before. The view contains many small, bri...
The Propeller Belts in Saturn's A Ring
From beneath the ring plane, the small, irregularly shaped moon Janus (181 kilometers, or 112 miles, across) can be seen following the orbital path it shares with slightly smaller Epimetheus (116 k...
Janus and Rings
This image of Ceres from NASA's Dawn spacecraft shows hummocky terrain -- a surface covered in low, rounded hills -- with numerous impact craters of varying sizes.
