NASA's Cassini spacecraft looks toward the night side of Saturn's moon Titan in a view that highlights the extended, hazy nature of the moon's atmosphere.

This image from NASA's Dawn spacecraft shows the texture of the surface in a part of asteroid Vesta's southern hemisphere. This region is just north of the main Rheasilvia structure.

Saturn's hazy moon Titan appears to drift above Saturn's ringplane in this view taken only a 10th of a degree above the rings. Titan's small orbital inclination is enough to make it appear above th...

Saturn's moon Titan displays a detached, high-altitude global haze layer which is often its most prominent feature in ultraviolet views such as this one. See Titan's Halo [Dec. 22, 2005] to learn ...

Dark material splatters the walls and floors of craters in the surreal, frozen wastelands of Iapetus. This image shows terrain in the transition region between the moon's dark leading hemisphere an...

The F ring shepherd moon Prometheus touches the face of Saturn once more before moving off into blackness and continuing in its orbit. The F ring itself is visible as a thin line just below Promet...

This image from NASA's Dawn spacecraft of asteroid Vesta shows Aelia crater, located in Vesta's Lucaria Tholus quadrangle, in Vesta's southern hemisphere.

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Gegania quadrangle, just south of Vesta's equator. Rubria is the crater with dark and bright material above Divalia Fossa an...

These two images, taken about eight minutes apart, show clump-like structures and a great deal of dust in Saturn's ever-changing F ring. The images show an object-interior to and detached from the ...

This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). Featured here is Dantu crater, named ...

With Cassini’s exploration of Saturn coming to a dashing end in a few months, the mission team scheduled an “All Cassini Plus Alumni” group photo to commemorate the event. 

Weather whirls on an alien world. Bright clouds swim in giant banks and shoals in Saturn's dreamlike atmosphere. With the Sun low on the horizon, the three-dimensional shape of the clouds becomes ...

The Cassini spacecraft looks toward a crescent of Saturn's moon Iapetus and glimpses a bit of that moon's yin-yang appearance. Scientists continue to investigate the nature of this moon's dark and...

Kerwan Crater, at 174 miles (280 kilometers) in diameter is the largest crater that NASA's Dawn has discovered on Ceres. A portion of its jagged rim runs from the top left to bottom center of this ...
