Arrival at Saturn

This image taken by NASA's Dawn spacecraft shows a region located next to the northwestern rim of Urvara Crater on Ceres. This terrain displays a rugged texture also found within Urvara.

This false-color infrared image, obtained by NASA's Cassini spacecraft, shows clouds of large ammonia ice particles dredged up by a powerful storm in Saturn's northern hemisphere. Large updrafts dr...

NASA's Dawn spacecraft captured this image of unnamed craters in the southern hemisphere of Ceres on Dec. 18, 2015. The image is centered at approximately 45 degrees south latitude, 325 degrees eas...

A Digital Video Disk (DVD) bearing 616,400 digitized signatures of people from nations around the world has been attached to the Cassini spacecraft and will soon be on its way to Saturn. The disk c...

As the Dawn spacecraft flies through space toward the dwarf planet Ceres, the unexplored world appears to its camera as a bright light in the distance, full of possibility for scientific discovery.

This synthetic aperture radar image of Titan was taken on Oct. 28, 2005, as the Cassini spacecraft flew by at a distance of 1,350 kilometers (840 miles). This was the first pass dedicated to radar...

These images from NASA's Dawn spacecraft show Sextilia crater on asteroid Vesta.

Feathery cloud bands fill Saturn's graceful crescent. Features in the atmosphere are visible all the way to the terminator, the boundary between night and day, where the Sun's rays are coming in al...

As Saturn's active moon Enceladus continues to spew icy particles into space, scientists struggle to understand the mechanics of what is going on beneath the fractured south polar terrain. This gra...

This enhanced color view from NASA's New Horizons spacecraft zooms in on the southeastern portion of Pluto's great ice plains, where at lower right the plains border rugged, dark highlands informal...

The plumes of Enceladus continue to gush icy particles into Saturn orbit, making this little moon one of a select group of geologically active bodies in the solar system. Enceladus (505 kilometers...

This montage of images shows the precise location of the north pole on Saturn's icy moon Enceladus.

This amazing close-up of Saturn's rings reveals their incredible variety. In some regions there are wavelike structures, while in other places the rings' structure appears to be more chaotic. This...

The Cassini spacecraft looks toward the wispy, fractured terrain of the trailing hemisphere of the moon Dione. To learn more about Dione's "wisps," see Wisps on Dione. Lit terrain seen here is o...

Since NASA's Cassini spacecraft arrived at Saturn in mid-2004, the planet's appearance has changed greatly.

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...

Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth ... ...
