These images from NASA's Dawn spacecraft are located in asteroid Vesta's Bellicia quadrangle, in Vesta's northern hemisphere.

Saturn's moons create art on the canvas of Saturn's rings with gravity as their tool. 

This view from NASA's Dawn spacecraft shows an unnamed Cerean crater that is surrounded by a smooth blanket of ejecta, including bright material. Both the area around the crater and its floor are p...

This movie, made from images obtained by NASA’s Cassini spacecraft of the outer edge of Saturn’s B ring, reveals the combined effects of a tugging moon and oscillations that can naturally occur in ...

This image from NASA's Dawn spacecraft of boulders along Urvara Crater's wall was obtained from an altitude of about 28 miles (45 kilometers) above Ceres' surface.

This high-resolution view shows incredible detail within a spiral density wave within Saturn's A ring. A spiral density wave is a spiral-shaped massing of particles that tightly winds many times a...

The famed wispy terrain on Saturn's moon Dione is front and center in this recent Cassini spacecraft image.

The Cassini spacecraft gazes into the blustery, ever changing atmosphere of Saturn as the tiny shadow of Epimetheus drifts across the cloud tops. The view looks toward a region in Saturn's atmosph...

Peering through Titan's thick haze, the Cassini spacecraft glimpses boundaries between bright and dark terrain on the moon's trailing hemisphere. The bright terrain at bottom is in northwestern Ad...

This image from NASA's Dawn spacecraft is dominated by a wide, young, fresh crater on asteroid Vesta. Surrounding this crater is its ejecta blanket, a covering of small particles that were thrown o...

In this sequence of four images taken during one night of observation by NASA's Catalina Sky Survey near Tucson, Arizona, the speck of light that moves relative to the background stars is a small a...

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...

Bright Venus seen near the crescent Moon in 2018.

N00151577.jpg was taken on February 13, 2010 and received on Earth February 15, 2010. The camera was pointing toward MIMAS at approximately 40,404 kilometers away, and the image was taken using the...

This image of a bright-rayed crater on giant asteroid Vesta was taken by the framing camera aboard NASA's Dawn spacecraft. The crater is about 2 miles (3.5 kilometers) in diameter and impacted on t...

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...

This image, obtained by NASA's Dawn spacecraft on June 9, 2018, shows subtle features on Ceres from an altitude of about 33 miles (53 kilometers).

The far side of Earth's Moon.

The conspicuous crater on the surface of Saturn's moon Mimas is seen in this image taken by Voyager. The massive crater, whose proportionate size (approximately 100 kilometers or 60 miles) is abo...

This map of Ceres, constructed from data collected by NASA's Dawn spacecraft, shows the dwarf planet's surface with features that have been named as of August 14, 2015.

This global digital map of Saturn's moon Rhea was created using data taken during Cassini and Voyager spacecraft flybys. The map is an equidistant projection and has a scale of 667 meters (2,188 fe...

Global images of Earth from Galileo. In each frame, the continent of Antarctica is visible at the bottom of the globe. South America may be seen in the first frame (top left), the great Pacific Oce...
