Two images of Saturn's A and B ring showcase the opposition effect, a brightness surge that is visible on Saturn's rings when the Sun is directly behind the spacecraft. This view is of the A ring....
Opposition Surge on the A Ring
Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth … no...
The Rite of Spring
A drawing illustrates how flows of electrons steered by Jupiter's magnetic field connect three of Jupiter's large moons with the upper atmosphere near Jupiter's north and south poles.
This image from NASA's Dawn spacecraft of Ceres shows a small, double-impact crater (at bottom) near a larger crater. The larger structure has a crater floor with roughly the same crater density.

Bright sunlight on Rhea shows off the cratered surface of Saturn's second largest moon. See Ancient Plains of Rhea and Bright Rays to learn more about this moon. Lit terrain seen here is on the ...
Reflecting on Icy Rhea
The number of water particles in Enceladus' plume peaked over the area highlighted by the circle in this image of Enceladus, which is overlain by data from Cassini's Ion and Neutral Mass Spectromet...
Peak Water Density
This image is a composite of several images taken during two separate Titan flybys on Oct. 9 (T19) and Oct. 25 (T20). The large circular feature near the center of Titan's disk may be the remnant ...
Exposing Titan's Surface
A darkly defined Rhea passes before the fuzzy orb of Titan in this Cassini view of Saturn's two largest moons. Rhea is closer to the spacecraft in this view. See Ancient Plains of Rhea to learn mo...

Titan's Polar Streak
Looking closely at Saturn's moon Rhea during a somewhat distant flyby, Cassini provides this view of what appears to be a bright, rayed and therefore relatively young crater. This crater was also o...

Gray Mimas appears to hover above the colorful rings. The large crater seen on the right side of the moon is named for William Herschel, who discovered Mimas in 1789. Images taken using red, gre...

The Cassini spacecraft looks toward the varied surface of the trailing hemisphere of Saturn's moon Enceladus. North on Enceladus (504 kilometers, or 313 miles across) is up. For a more detailed vi...
Presented here are side-by-side comparisons of a traditional Cassini Synthetic Aperture Radar (SAR) view, at left, and one made using a new technique for handling electronic noise that results in c...

Two Waves in One Spectacular Image of Saturn's Rings
Saturn's moon Janus, its rugged surface shown in shadow and light, passes before the planet's rings. See Crater View to see a closer view of this moon. Janus (179 kilometers, or 111 miles across) ...
Janus Before the Rings
Dione reveals its past via contrasts in this view from NASA's Cassini spacecraft. The features visible here are a mixture of tectonics -- the bright, linear features -- and impact cratering -- the ...

This image from NASA's Dawn spacecraft shows an escarpment located in asteroid Vesta's near Rheasilvia quadrangle, near Vesta's south pole.
Escarpment on Vesta
Saturn's moon Enceladus, seen beyond the outline of the planet's night side, spews water ice from its south polar region. Enceladus is farther from Cassini than the planet is here. The plumes can ...
