Dione, Enceladus, and Saturn's Rings

While not bursting with activity like its system satellite Enceladus, the surface of Dione is definitely not boring.

Planetary Ring Riddle Solved

Planetary Ring Riddle Solved

In a breakthrough study scientists have solved an age-old scientific riddle by discovering that planetary rings, such as those orbiting Saturn, have a universally similar particle distribution.


Unusual Red Arcs Spotted on Tethys

Unusual Red Arcs Spotted on Tethys

Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn's icy moon Tethys in new, enhanced-color images from NASA's Cassini spacecraft.


Three Crescent Moon Orbiting Saturn

Three Crescent Moon Orbiting Saturn

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.


Z Machine Helps Solve Saturn's Two Billion-year Age Problem

Z Machine Helps Solve Saturn's Two Billion-year Age Problem

Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source.


Stunning View of Dione, Enceladus, and Saturn's Rings

Stunning View of Dione, Enceladus, and Saturn's Rings

NASA's Cassini imaging scientists processed this view of Saturn's moon Dione, taken during a close flyby on June 16, 2015.


Understanding The Surface Geology of Titan

Understanding The Surface Geology of Titan

Saturn's moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what makes the depressions they lie in? A new study suggests that the moon's surface dissolves in a similar process that creates sinkholes on Earth.


Small Thunderstorms May Add Up To Massive Cyclones on Saturn

Small Thunderstorms May Add Up To Massive Cyclones on Saturn

For the last decade, astronomers have observed curious "hotspots" on Saturn's poles. In 2008, NASA's Cassini spacecraft beamed back close-up images of these hotspots, revealing them to be immense cyclones, each as wide as the Earth.


First Look at Hyperion Flyby Images

First Look at Hyperion Flyby Images

This image was taken on May 31, 2015 and received on Earth June 01, 2015. The camera was pointing toward HYPERION, and the image was taken using the IR2 and CL2 filters.


Cassini Prepares for Last Up-close Look at Hyperion

Cassini Prepares for Last Up-close Look at Hyperion

NASA's Cassini spacecraft will make its final close approach to Saturn's large, irregularly shaped moon Hyperion on Sunday, May 31.


Activity on Enceladus Could Be

Activity on Enceladus Could Be "Curtain Eruptions" Video in Story

New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets.


Saturn's Sponge-like Moon Hyperion

Saturn's Sponge-like Moon Hyperion

The subject of this image bears a remarkable resemblance to a porous sea sponge, floating in the inky black surroundings of the deep sea.


Violent Methane Storms on Titan May Explain Dune Direction

Violent Methane Storms on Titan May Explain Dune Direction

With its thick, hazy atmosphere and surface rivers, mountains, lakes and dunes, Titan, Saturn's largest moon, is one of the most Earthlike places in the solar system.


Explaining Saturn's Epic Storms

Explaining Saturn's Epic Storms

The long-standing mystery of why Saturn seethes with enormous storms every 30 years may have been solved by scientists working with data from NASA's Cassini mission.


Icy Tendrils Reaching into Saturn Ring Traced to Their Source

Icy Tendrils Reaching into Saturn Ring Traced to Their Source

Long, sinuous, tendril-like structures seen in the vicinity of Saturn's icy moon Enceladus originate directly from geysers erupting from its surface, according to scientists studying images from NASA's Cassini spacecraft.


Cassini's New View of Rhea

Cassini's New View of Rhea

A dual view of Saturn's icy moon Rhea marks the return of NASA's Cassini spacecraft to the realm of the planet's icy satellites.
