Great Dark Spot

This image, taken on June 17, 2015 by NASA's Dawn spacecraft, shows dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers) with a resolution of 1,400 feet (410 meters) per pixel. A b...

Great circular vortices churn through Saturn's northern skies. The planet wears the shadow of its rings as a dark belt. Just above that belt is the shadow of 181-kilometer (113-mile) wide Janus. ...

This animation shows the Cassini spacecraft approaching Titan. The strips of data on the globe represent areas observed with the Cassini radar instrument. The pink swatch is the area observed by ...

Saturn casts a wide shadow across its rings in this Cassini spacecraft view which looks toward the darkened southern hemisphere of the night side of the planet. See Light and Dark Tricks and Activ...

Cassini's cameras were retargeted to capture the tiny Keeler Gap moon S/2005 S1, visible at the center and first discovered by Cassini a few months ago. Waves raised in the gap edges by the Keele...

Shadows cast by Saturn's rings separate the planet's bright equatorial band from the darker northern latitudes. This view makes use of a spectral filter sensitive to absorption of certain waveleng...

A comparison image shows how Martian winds help clean the Opportunity rover's solar panels over three months in 2014. 

The Cassini spacecraft looks toward the innermost region of Saturn's rings, capturing (from right to left) the C and B rings. The dark, inner edge of the Cassini Division is just visible in the low...

This image, taken by NASA's Dawn spacecraft, shows the southeastern rim of Occator Crater. Compacted material forms spurs along the crater wall. A group of roughly parallel, braided fractures can b...

Saturn's moon Hyperion's crater, Meri, blooms in this extreme color-enhanced view. Meri is overprinted by a couple of smaller craters and displays dark material on its floor that is characteristic ...

This anaglyph from NASA's Dawn spacecraft shows three fresh craters on asteroid Vesta, which have been nicknamed the 'Snowman' craters. You need 3D glasses to view this image.

Ligeia Mare, shown here in a false-color image from NASA's Cassini mission, is the second largest known body of liquid on Saturn's moon Titan.

Mariner 10 was launched on November 3, 1973, 12:45 am PST, from Cape Canaveral on an Atlas/Centaur rocket (a reconditioned Intercontinental Ballistic Missile - ICBM).

What appear to be spiders scampering across the martian landscape are actually cracks in the surface of the southern polar region on Mars, seen by the Mars Reconnaissance Orbiter on August 23, 2009.

This colorized map from NASA's Dawn mission shows the types of rocks and minerals distributed around the surface of the giant asteroid Vesta.

+ Un-annotated version The constant change in Saturn’s wavy, wiggly F ring is on display in this set of images obtained by NASA’s Cassini spacecraft. The images show a view looking directly down o...

This view from NASA's Dawn spacecraft shows two medium-sized craters at high northern latitudes on Ceres.

Clumps of ring material are revealed along the edge of Saturn's A ring in this image taken during the planet's August 2009 equinox. The granular appearance of the outer edge of the A ring, first d...

Pan is nearly lost within Saturn's rings in this view that captures a small section of the rings from just above the ringplane. Pan (28 kilometers, or 17 miles across) appears a small bright dot o...

Seen here is the end result of the process that occurs every time the moon Prometheus closely approaches Saturn's F ring. The moon cuts a dark channel in the ring's inner edge that then shears out ...

Southern Storms and Streaks September 15, 2004 Full-Res: PIA06477 The region near Saturn's south pole shows a great deal of fascinati...

In Saturn's bluish north, day ends for the dreamy white clouds that stretch here into twilight. This natural color scene shows middle latitudes in Saturn's north at excellent resolution, and with ...

This southerly view of Dione shows enormous canyons extending from mid-latitudes on the trailing hemisphere, at right, to the moon's south polar region. This view looks toward the Saturn-facing si...

Zooming In On Titan October 25, 2004 Full-Res: PIA06116 This map of Titan's surface, generated from images taken during Cassini's...

Streaks of cloud are overlain with graceful ring shadows in this view of Saturn's northern latitudes. Structure is visible in the shadow of the A ring and Cassini Division, which widen at the hig...
