Io in Eclipse

The Cassini spacecraft has been monitoring propeller features since their discovery. Here the propeller dubbed Bleriot is seen in a recent image. The bright dash-like features are regions where a s...

Ithaca Chasma is one of the two most prominent features on Saturn's moon Tethys; the other is the gigantic crater Odysseus. Ithaca Chasma is visible near the moon's lower right limb in this image, ...

A wide crater dominates the lower right of this image while part of Rhea's brightly lit, wispy terrain can still be seen near the limb of the moon. Smaller craters are overprinted upon this crater,...

This image of Urvara Crater was obtained by NASA's Dawn spacecraft on May 20, 2018 from an altitude of about 920 miles (1480 kilometers).

A single crescent moon is a familiar sight in Earth's sky, but with Saturn's many moons, you can see three or even more.

The effects of the moon Prometheus create intricate formations in Saturn's thin F ring. The gravity of potato-shaped Prometheus (86 kilometers, or 53 miles across) periodically creates streamer-ch...

Launched on March 2, 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt, and the first spacecraft to make direct observations and obtain close-up images of Jupiter. 

This almost surreal view of Iapetus was acquired by Cassini about 10 minutes after the spacecraft's closest approach to the icy moon during a close flyby on New Year's Eve 2004.

This is the separate version of the infrared image that accompanies the feature Cassini Sees Saturn Storm's Explosive Power The visible-light image can be seen separately here: Catching Its Tail...

Slipping into shadow, the south polar vortex at Saturn's moon Titan still stands out against the orange and blue haze layers that are characteristic of Titan's atmosphere.

This set of three images shows views three seconds apart as the larger of Mars' two moons, Phobos, passed directly in front of the sun as seen by NASA's Mars rover Curiosity.

The shadow of Saturn's moon Dione, cast onto the planet, is elongated in dramatic fashion. The moon itself does not appear here, but the shadow can be seen south of the ringplane. This view looks ...

This bizarre scene shows the cloud-streaked limb of Saturn in front of the planet's B ring. The ring's image is warped near the limb by the diffuse gas in Saturn's upper atmosphere. For additional...

Hyperion, the eighth largest of Saturn's nearly 60 known moons, is covered in craters and landslides. Sprinkled over the icy surface is a thin layer of organic dust, which has somehow been concentr...

The Cassini spacecraft looks over cratered and tectonically deformed terrain on Saturn's moon Enceladus as the camera also catches a glimpse of the planet's rings in the background. The image was c...

Titan's Mottled Surface July 3, 2004 Full-Res: PIA06109 Shown here is a mosaic of Titan's south polar region acquired as Cassini ...

This Cerean crater, which is covered in ridges and steep slopes, called scarps, was captured by NASA's Dawn spacecraft on Dec. 23, 2015. These features likely resulted when the crater partly collap...

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. 29, 2015, and ha...

The huge Odysseus Crater disfigures the face of Saturn's moon Tethys. The crater, in the top right of the image, is 450 kilometers, or 280 miles, across (see The Great Basin for more information)....

Some might see a pancake, and others a sand dollar, in this new image from NASA's Dawn mission. Astronomers are puzzling over a mysterious large circular feature located south of the equator and sl...

This image was taken on 2017-09-08 07:01 (PDT) and received on Earth 2017-09-09 12:58 (PDT).

Two-Tone Titan June 16, 2004 Full-Res: PIA05407 Cassini¿s finely-tuned vision reveals hazes high in the skies over Titan in this ...

Saturn's shepherd moon Prometheus reveals its elongated, irregular form to Cassini in this image. The moon's long axis points toward Saturn. Prometheus is 102 kilometers (63 miles) across. This vi...

This image from NASA's Dawn spacecraft shows the edge of Ikapati crater on Ceres, at upper right. Dawn took this image on June 12, 2016, from its low-altitude mapping orbit, at a distance of about ...

Possible variations in chemical composition from one part of Saturn's ring system to another are visible in this Voyager 2 picture as subtle color variations that can be recorded with special compu...
