This amazing perspective view captures battered Mimas against the hazy limb of Saturn. It is obvious in such close-up images that Mimas (397 kilometers, or 247 miles across) has been badly scarred...

This movie, showing six of Saturn's small ring-region moons as they raced around the planet, was made from images taken by the Cassini spacecraft on Nov. 15, 2004. The moons appear in following or...

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

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 7, 2015, from a distance of 8,400 miles (13,600 kilometers).

From just above the plane of Saturn's rings, the Cassini spacecraft snapped this shot of Saturn two months after Saturn's August 2009 equinox, showing the shadow of its rings as a narrow band on th...

Saturn's icy moon Rhea passes in front of Titan as seen by NASA's Cassini spacecraft in 2009.

It is spring in the Northern hemisphere when NASA's Mars Reconnaissance Orbiter took this image.

It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 miles (45,000 kilometers) away from the rings.

This image from NASA's Dawn spacecraft shows a part of the heavily cratered terrain in asteroid Vesta's northern hemisphere. Some of the craters have fresh, sharp rims, which suggests that they are...

Cassini stared toward Saturn's two-toned moon Iapetus (914 miles or 1,471 kilometers across) for about a week in early 2015, in a campaign motivated in part to investigate subtle color differences ...

Eleven years in the life of the Sun, spanning most of solar cycle 23.

Titan's Atmosphere This graphic illustrates the differences in Titan's and Earth's atmospheres. Titan's atmosphere extends 10 times further into space than Earth's.

This picture is a composite of 30 images from ESA's Huygens probe. They were taken from an altitude varying from 13 kilometers down to 8 kilometers when the probe was descending towards its landing...

Fine, sharp-edged details and smooth gradients in the ring features of the Cassini Division are imaged here together at excellent resolution. The faint ringlet in the dark gap left of center is a ...

This false-color Cassini mosaic of Saturn's moon Enceladus captures in a single view, much of the frigid moon's diverse geology.

This image from NASA's Dawn spacecraft of asteroid Vesta shows Drusilla crater, which is the irregularly shaped crater offset from the center of the image.

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...

Jupiter Clouds, True Color and False to Show Heights January 23, 2001 These two frames of composited images taken by NASA's Cassini spacecraft show the same cloud patterns on Jupiter bot...

Dione looks lovely half lit in this portrait from the Cassini spacecraft. Just visible is a long canyon running southward just left of the terminator. The view looks down at northern latitudes on ...

Saturn's rings lie in the distance as the Cassini spacecraft looks toward Titan and its dark region called Shangri-La, east of the landing site of the Huygens Probe. See Hugyens' Landing Site and...

The Cassini spacecraft looks down on the north pole of Mimas and sees the moon's cratered trailing hemisphere. The moon's north pole lies on the terminator about a quarter of the way inward from t...

These images from NASA's Dawn spacecraft show part of the rim of asteroid Vesta's south polar basin, which is dominated by a large scarp (cliff) that runs vertically across the center of the images.

For Enceladus, wrinkles mean the opposite of old age. This view of a crescent Enceladus shows a transition zone between a wrinkled and presumably younger region of terrain and an older, more heavil...

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 in gaps in Cassini's...
