Great Dark Spot
Twice as far from the Sun as Jupiter, Saturn's colder temperatures mean that clouds form lower in its atmosphere. As a result, the visible cloud patterns - so striking on Jupiter - occur deeper ins...
This Cassini image shows the night side of Saturn's moon Dione, dimly lit by "Saturnshine": that is, reflected light from the planet lying off to the left in Cassini's field of view when this imag...
Using its radar system, the Cassini spacecraft has imaged new lakes on Titan. The large dark patch seen on this image, at high latitudes surrounding Titan's north pole, is most likely a hydrocarb...
Titan's Great Lakes?
The great eye of Saturn's moon Mimas (MY-muss), a 130-kilometer-wide (80-mile) impact crater called Herschel, stares out from the battered moon in this raw image taken by the Cassini spacecraft dur...
Cassini's Flies by "Death Star" Moon
Few large craters are to be found in the wrinkled terrain of Enceladus, where the surface has been reworked by geologic processes presumably resulting from the moon's inner warmth. Cassini spied t...
Moon With a Warm Heart
Since its discovery in 2005, Pluto's moon Hydra has been known only as a fuzzy dot of uncertain shape, size, and reflectivity.
Hydra Emerges from the Shadows
In this artist's rendering, a distant sun forms a halo (refracted sunlight by ice crystals) amid streamers of pure water ice particles, which spew into space from cracks in the south polar surface ...

Galileo Galilei's observations that Venus appeared in phases -- similar to those of Earth's Moon -- in our sky was evidence that Venus orbited the sun and contributed to the downfall of the centuri...

This image is one several images NASA's Dawn spacecraft took on approach to Ceres on Feb. 4, 2015 at a distance of about 90,000 miles (145,000 kilometers) from the dwarf planet.

Radiant Dione (Raw Image)
Seasonal twilight is approaching for Saturn's south polar vortex -- the giant hurricane-like storm swirling around the planet's southern pole. When the Cassini spacecraft arrived at Saturn in mid-...

This image of bright material in Occator Crater on Ceres was obtained by NASA's Dawn spacecraft on July 5, 2018 from an altitude of about 34 miles (55 kilometers).
Bright Material in Occator Crater
This natural color view from the Cassini spacecraft highlights the myriad gradations in the transparency of Saturn's inner rings. The dark shadows of the rings separate Saturn's southern hemispher...
This view of Ceres from NASA's Dawn spacecraft, taken on May 29, 2016, features a small crater at upper left that adjoins Messor Crater.
Dawn LAMO Image 162
The Cassini spacecraft looks across the unlit ringplane as Mimas glides silently in front of Dione. It is often difficult to tell from two-dimensional views like this where the moons are in relati...
The moon Pandora casts a shadow onto Saturn's A ring but not the F ring. Pandora (81 kilometers, or 50 miles across) can be seen at the bottom of the image. Because Pandora is on an inclined orbit...
Shadow Misses a Ring
These images from NASA's Dawn spacecraft are located in asteroid Vesta's Gegania quadrangle, a little south of Vesta's equator; boulders can be seen on the bottom side of the crater.
HAMO and LAMO Images of Rubria Crater
Tethys, dwarfed by the scale of Saturn and its rings, appears as an elegant crescent in this image taken by NASA's Cassini Spacecraft. Views like this are impossible from Earth, where we only see S...

Enceladus Transits Rhea
Saturn, which appears as only a thin, lit crescent, broken only by the shadows of its rings, poses gracefully for the Cassini spacecraft cameras.
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,...
