Io in Eclipse

This time-lapse video captures a portion of the path that tiny Phobos takes around Mars. 

Saturn has 31 known satellites. They vary greatly in size, shape and appearance.

Shadows seem ubiquitous in this Cassini spacecraft view of Saturn's rings captured shortly after the planet's August 2009 equinox. The moon Pan (28 kilometers, or 17 miles across) casts a long sha...

This composite image NASA's Dawn spacecraft is a simulated true color image of part of asteroid Vesta's south polar region.

NASA's Cassini spacecraft obtained this unprocessed image of Saturn's moon Helene on June 18, 2011. This image has not been validated or calibrated. A validated/calibrated image will be archived w...

Cassini acquired this view of Titan on April 13, 2007, following a flyby of the Mercury-sized moon. Titan's equatorial dark regions are visible in this view, along with faint, dark lineaments (line...

The dark side of the ringplane glows with scattered light, including the luminous F ring, which shines like a rope of brilliant neon. Below, Dione (1,126 kilometers, or 700 miles across) presents a...

The Cassini spacecraft peers through the atmosphere of Saturn's largest moon, Titan, to examine the dark region Belet. This large region on the moon's surface has a low albedo, meaning it reflects...

As it approached Titan for yet another revealing encounter, the Cassini spacecraft acquired this image showing terrain on the moon's Saturn-facing hemisphere. Prominent dark areas found in the moo...

Mercury astronaut Scott Carpenter stands in front of the NASA insignia at Cape Canaveral.

Saturn’s unusual appearance in this picture is a result of the planet being imaged via an infrared filter.

This image obtained by NASA's Dawn spacecraft shows a field of small craters next to Kokopelli Crater, seen at bottom right in this image, on dwarf planet Ceres.

The Cassini spacecraft stares at the Huygens Gap -- the region between Saturn's outer B ring and the ringlets of the prominent Cassini Division -- in this high-resolution view. Ring scientists thi...

This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres at mid-latitudes from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 21, 2015, and ha...

The flattened, potato-like form of Prometheus glides silently within the Roche Division, between Saturn's A and F rings.

This figure examines a particularly strong jet stream and the eddies that drive it through the atmosphere of Saturn's northern hemisphere. Data from NASA's Cassini spacecraft were used to create th...

A great vortex, ringed by bright clouds, rolls through the southern skies of Saturn in this Cassini spacecraft view. The image was taken using a spectral filter sensitive to wavelengths of infrare...

This shaded relief image of Mexico's Yucatan Peninsula show a subtle, but unmistakable, indication of the Chicxulub impact crater.

Saturn's icy moon Mimas is dwarfed by the planet's enormous rings.

Dr. Wernher von Braun explains the Saturn V Launch System to President John F. Kennedy.

Newly assembled radar images from the Cassini spacecraft provide the best view of the hydrocarbon lakes and seas on the north pole of Saturn's moon Titan, while a new radar image reveals that Titan...

Bright light reflects off the wispy terrain of Saturn's moon Rhea in this image which looks down on the high northern latitudes of the icy moon. Lit terrain seen here is on the trailing hemisphere...
