The shadow of the moon Enceladus appears on Saturn just south of the thin shadow of the planet's rings in this image captured shortly after Saturn's August 2009 equinox. Enceladus (504 kilometers,...
Shadow South of Another
Scarred and battered Rhea fills the Cassini spacecraft's view. Notable here is the sharp relief of steep crater walls near the terminator. Icy Rhea (1,528 kilometers, or 949 miles across) is Satur...
The Cassini spacecraft looks past Saturn's rings and small moon Janus to spy the planet's second largest moon, Rhea. Janus is closest to Cassini here. The rings are between Janus (179 kilometers, ...

This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA's Cassini spacecraft on December 29, 2000, during its closest approach to the giant plane...

Named after a Japanese paradise, the Senkyo region of Titan (the dark area below and to the right of center) is a bit less welcoming than its namesake.

The longest-lived continuously monitored electrical storm ever observed on Saturn continues to churn through the tempest-tossed region nicknamed "Storm Alley" because of its preponderance of storm ...
The Cassini spacecraft captures a gathering of three moons near the rings' outer edge as the icy worlds dutifully march about Saturn. Tethys (1,071 kilometers, or 665 miles across) hangs in front ...
Parade of Moons
Capturing the interplay between light and shadow, the Cassini spacecraft looks toward the night side of Saturn where sunlight reflected off the rings has dimly illuminated what would otherwise be t...

NASA's Dawn spacecraft obtained this false-color image of asteroid Vesta's equatorial region with its framing camera on July 25, 2011.

These two 591-second exposures of the rings of Neptune were taken with the clear filter by the Voyager 2 wide-angle camera on Aug. 26, 1989 from a distance of 280,000 kilometers (175,000 miles).
Rings of Neptune
The shadow of the moon Tethys is cast onto Saturn's A ring, almost blanketing the Enke Gap. The novel illumination geometry created as Saturn approaches its August 2009 equinox allows moons orbiti...
Engulfing a Gap
With streaks of icy material thrown in many directions, a huge ray crater stretches across nearly half of the leading hemisphere of Saturn's moon Rhea. With the sun almost directly behind the spac...

This map of the surface of Iapetus, generated from images taken by NASA's Cassini and Voyager spacecraft, illustrates the imaging coverage planned for Cassini's very close flyby of the two-toned mo...

This image from NASA's Dawn spacecraft shows a young crater on asteroid Vesta.

Janus coasts past as the Cassini spacecraft takes in a view of the unilluminated side of the rings. Bright regions within the rings appear so because they allow scattered sunlight to filter through...

The Cassini data presented in this view appear to confirm a region of warm atmospheric descent into the eye of a hurricane-like storm locked to Saturn's south pole. The view shows temperature data ...
The Hole at the Pole
The Cassini spacecraft looks toward the dark Senkyo region on Saturn's moon Titan. Senkyo is the dark region towards the right. Two other dark regions, Aztlan (to the left, slanting down below the...

NASA's Dawn spacecraft imaged this terrain, adjacent to Occator Crater on Ceres, which is immediately to the left of this view. This relatively smooth, lightly cratered area is part of the ejecta b...

This image was acquired on 28 July 2008 with the nadir channel of the High Resolution Stereo Camera.
Close-Up of Phobos from Mars Express
Although the rings lack the many colors of the rainbow, they arc across the sky of Saturn. From equatorial locations on the planet, they'd appear very thin since they would be seen edge-on.
Not since NASA's Voyager 1 spacecraft saw our home as a pale blue dot from beyond the orbit of Neptune has Earth been imaged in color from the outer solar system. Now, Cassini casts powerful eyes o...
Pale Blue Orb (1)
This view from NASA's Dawn spacecraft shows an impact site at high southern latitude on Ceres. A smooth blanket of ejecta surrounds the crater. Many boulders can be seen around the crater's rim and...
Dawn LAMO Image 52
This sequence of images shows a faint arc of material in Saturn's G ring, a tenuous ring outside the main ring system. These images were each taken about 45 minutes apart. During this time, the arc...
