Past and Present Moons of Saturn

Saturn's beautiful rings form a striking feature, cutting across this image of two of the planet's most intriguing moons.

Tethys and Janus

Although Tethys and Janus both orbit Saturn and are both made of more or less the same materials, they are very different worlds. Their contrasts are related, in large part, to their sizes.

Saturn's Rings - Less than Meets the Eye?

It seems intuitive that an opaque material should contain more stuff than a more translucent substance.

Viewing Methane On Saturn

The soft, bright-and-dark bands displayed by Saturn in this view from NASA's Cassini spacecraft are the signature of methane in the planet's atmosphere.

Appreciating The Immense Size of Saturn

It is easy to forget just how large Saturn is, at around 10 times the diameter of Earth.

Dione and Saturn's Rings

Dione's beautiful wispy terrain is brightly lit alongside Saturn's elegant rings.

Close Up View of Prometheus

NASA's Cassini spacecraft spied details on the pockmarked surface of Saturn's moon Prometheus (86 kilometers, or 53 miles across) during a moderately close flyby on Dec. 6, 2015.

Tethys and Saturn

Tethys, dwarfed by the scale of Saturn and its rings, appears as an elegant crescent in this image taken by NASA's Cassini Spacecraft.

A University of Alberta researcher has successfully generated 3D simulations of deep jet streams and storms on Jupiter and Saturn, helping to satiate our eternal quest for knowledge of planetary dynamics.

A Crescent Enceladus And Saturn's Rings

Although Enceladus and Saturn's rings are largely made up of water ice, they show very different characteristics.

Comparing Enceladus and Dione

Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky.

New Closeup Images of Enceladus

This image of Enceladus was taken on October 14, 2015 and received on Earth October 15, 2015.

Mimas, Pandora and Saturn's Rings

This view looks toward the unilluminated side of the rings from 0.26 degrees below the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 26, 2015.

Chasms on Dione

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

Looking at Saturn in the Infrared

Saturn's unusual appearance in this picture is a result of the planet being imaged via an infrared filter.

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

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.

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

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

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.
