Great Dark Spot
Weak sunlight illuminates Saturn's large, icy moon Tethys and its giant crater Odysseus. At the orbit of Saturn the Sun's light is between 80 and 100 times fainter than at Earth, depending on whe...
Although most of the region observed by the Cassini radar instrument in the February close flyby of Titan is very different from the regions imaged in October, the area shown in this image appears ...
These images from NASA's Dawn spacecraft are located in asteroid Vesta's Gegania quadrangle, just south of Vesta's equator. Rubria, with dark and bright material is above Divalia Fossa, and Occia, ...

This image of Claudia AV-L-23, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.
This image is one several images NASA's Dawn spacecraft took on approach to Ceres on Feb. 4, 2015 at a distance of about 90,000 miles (145,000 kilometers) from the dwarf planet.

W00004705.jpg was taken on February 15, 2005 and received on Earth February 15, 2005. The camera was pointing toward TITAN, and the image was taken using the CL1 and CB3 filters. This image has not...
Titan bears a distinct east-west banded pattern in this Cassini spacecraft image taken in the ultraviolet. The ultraviolet wavelength allows Cassini to see Titan's stratosphere, where superrotatio...

Stunning details in Saturn's clouds suggest movement within bands of atmosphere. This false color enhancement makes visible an exciting level of detail in the bright and dark bands that is more eas...
Like hunters sighting a clay duck flying fast in the sky, Cassini obtained this mosaic from narrow camera angle 'skeet-shoot' images 1, 2, 3 and 4, all captured during the rapid Oct. 31, 2008, flyb...
