The craters in the image, taken Oct. 1, 2015 from NASA's Dawn spacecraft, are characterized by different degrees of freshness, reflecting different ages. The sharply defined crater to right of cent...

This oblique view of Saturn's moon Iapetus from high latitude shows how the dark, heavily cratered terrain of Cassini Regio transitions to a bright, icy terrain at high latitudes. In this mosaic o...

A 1909 VDB penny sent to Mars aboard the Curiosity rover as part of an image calibration target (and a nod to a geology tradition of using a coin for scale). 

The slim crescent of Ceres smiles back as the dwarf planet awaits the arrival of an emissary from Earth. This image was taken by NASA's Dawn spacecraft on March 1, 2015.

Lakes on Saturn's moon Titan reflect radio waves in varying ways in this image from NASA's Cassini spacecraft. Scientists think the variations in reflectivity, or brightness, have to do with the sm...

This image shows a rare and powerful storm on the night side of Saturn. Light from Saturn's rings (called "ringshine") provided the illumination, allowing the storm and other cloud features to be ...

This still is from a short computer-animated film that highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017. Download the vi...

Four moons huddle near Saturn's multi-hued disk.

Arrival at Saturn

This image from NASA's Dawn spacecraft of asteroid Vesta shows the characteristic undulating surface of Vesta's southern hemisphere and many small craters, some of which make up secondary crater ch...

Soaring above the alien, icy wastelands of Saturn's moon Iapetus, NASA's Cassini spacecraft captured a series of high-resolution images of the transition region from dark to bright terrain at south...

''It's full of stars!'' the character Bowman proclaimed in 2001: A Space Odyssey.This Cassini spacecraft view evokes the exclamation, ''It's full of moons!'' Saturn possesses no less than 52 offic...

This image, taken by NASA's Dawn spacecraft, shows high southern latitudes on Ceres from an altitude of 2,700 miles (4,400 kilometers). Zadeni crater, measuring about 80 miles (130 kilometers) acro...

This infrared image from Juno gives an unprecedented view of the southern aurora of Jupiter.

Note: This image has been rotated 180 degrees from its original orientation published on Feb. 2, 2010. Caption updated July 28, 2014 Dramatic plumes, both large and small, spray water ice and vap...

Two pairs of Storms June 4, 2004 Full-Res: PIA05401 Two pairs of dark spots, or storms, in Saturn's atmosphere squeeze past each ...

The existence of oceans or lakes of liquid methane on Saturn's moon Titan was predicted more than 20 years ago. 

These composite images from NASA's Dawn spacecraft images show the spectacular spectral diversity of asteroid Vesta's surface.

Among the interplay of Saturn's shadow and rings, Mimas, which appears in the lower-right corner of the image, orbits Saturn as a set of the ever-intriguing spokes appear in the B ring (just to the...

Twenty-eight years before Cassini-Huygens arrived at Saturn, artist Ken Hodges painted this vision of a possible mission to explore Saturn and the giant moon Titan for NASA's Jet Propulsion Laborat...

+ Annotated version The northern and southern hemispheres of Rhea are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager images. Six Voyager images fill...

This image (N00156648.jpg) was taken on July 05, 2010 and received on Earth July 06, 2010. The camera was pointing toward DAPHNIS, and the image was taken using the BL1 and CL2 filters. This image ...

Cassini instruments provide complementary information about the structure of Saturn's rings. Narrow and wide angle cameras provide images in the visible region of the electromagnetic, spectrum much...

Cassini's best close-up view of Saturn's F ring shepherd moon, Pandora, shows that this small ring-moon is coated in fine dust-sized icy material.

This image high-resolution image of Juling Crater on Ceres, taken by NASA's Dawn spacecraft, reveals, in exquisite detail, features on the rims and crater floor.
