Io Color Eclipse

Using visible light, astronomers for the first time this century have detected clouds in the northern hemisphere of Uranus. 

Epimetheus is one of Saturn's "co-orbital moons" because it shares nearly the same orbit as Janus at a distance of approximately 151,000 kilometers (94,000 miles) from Saturn. Epimetheus is 116 kil...

Three different false-color views of Saturn's moon Iapetus show the boundary of the global "color dichotomy" on the hemisphere of this moon facing away from Saturn. The "color dichotomy," which has...

All of NASA’s science missions are driven by powerful questions to help us better understand our planet, our solar system, and beyond. What vibrant colors will you bring to these scenes of explorat...

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...

In this image, Saturn's fascinating meteorology manifests itself in a "string of pearls" formation, spanning over 60,000 kilometers (37,000 miles). Seen in new images acquired by Cassini's visual ...

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 image from NASA's Dawn spacecraft shows a portion of Ikapati Crater on Ceres. Dawn took this image on June 10, 2016, from its low-altitude mapping orbit, at a distance of about 240 miles (385 ...

Accompanied by their teacher, Kathy Cooper, a group of students from Shirley Avenue Elementary School in Reseda, California, pose in front of a half-scale model of the Cassini spacecraft at JPL. T...

Sunlight illuminates the deep cut of Ithaca Chasma on Saturn's moon Tethys.

The brilliant B ring ends abruptly at the Huygens Gap -- the broad, dark band devoid of ring material seen here near left.

This bright, isolated plateau in the middle of the C ring displays interesting internal variations in brightness. The plateau is not high in terms of elevation, but rather in terms of its particle ...

This image from NASA's Dawn mission shows a shadowy view of the northern hemisphere of the giant asteroid Vesta during Dawn's last look back.

A large crater on Saturn's tiny moon Janus is distinctly visible in this Cassini spacecraft image. Lit terrain seen here is on the leading hemisphere of Janus (179 kilometers, or 111 miles across)...

Saturn's moon Daphnis, appearing as a tiny speck in the Keeler Gap of the A ring on the far right of this Cassini spacecraft image, is almost lost among the moon's attendant edge waves. Daphnis (8...

The orbits of Dione and Titan bring them together in one frame in this distant glimpse from the Cassini spacecraft. Light and dark areas on Dione (1123 kilometers, or 698 miles across), at the top...

Swirling clouds drift like phantoms in Saturn's murky depths. The camera filter used for this image captures light at wavelengths where atmospheric gases like methane are fairly transparent, allow...

This image of Ceres from NASA's Dawn spacecraft shows a crater near the dwarf planet's equator. The view is centered at approximately 6 degrees south latitude, 230 degrees east longitude.

This figure illustrates the unexpected and bizarre pattern of daytime temperatures found on Saturn's small inner moon Mimas (396 kilometers, or 246 miles, in diameter). 

Appearing like a freckle on the face of Saturn, a shadow from the moon Enceladus blemishes the planet just below the ringplane in this Cassini spacecraft image. Enceladus is not shown here. This v...

NASA's Dawn mission has found that craters on Ceres show a diversity of shapes that provide important clues about the structure of Ceres' subsurface; shown here is Fejokoo, a polygonal crater.

Cassini conducts its first close flyby of Saturn's icy moon Enceladus (en-SELL-uh-duss) at a distance of approximately 1,180 kilometers (730 miles). Enceladus' is one of the most reflective object...

The profile of the 450-kilometer-wide (280-mile) crater Odysseus makes this image look as if someone sliced off a chunk of Tethys (1,071 kilometers, or 665 miles across). According to measurements ...

Saturn's small moon Pan, brightly overexposed, casts a short shadow on the A ring in this image taken before the planet's August 2009 equinox. Pan (28 kilometers, or 17 miles across) orbits in the...
