Cassini Makes First Ring-Grazing Plunge

NASA's Saturn-orbiting Cassini spacecraft has made its first close dive past the outer edges of Saturn's rings since beginning its penultimate mission phase on Nov. 30.

The Birth of Saturn's Rings

A team of researchers have presented a new model for the origin of Saturn's rings based on results of computer simulations.

The Fluid Dynamics of Saturn's Clouds

Saturn's clouds are full of raw beauty, but they also represent a playground for a branch of physics called fluid dynamics, which seeks to understand the motion of gases and liquids.

Cassini Begins Final Year at Saturn

After more than 12 years studying Saturn, its rings and moons, NASA's Cassini spacecraft has entered the final year of its epic voyage.

Watching Saturn's Rings Warp

Saturn's A and F rings appear bizarrely warped where they intersect the planet's limb, whose atmosphere acts here like a very big lens.

A bright disruption in Saturn's narrow F ring suggests it may have been disturbed recently.

During a recent stargazing session, NASA's Cassini spacecraft watched a bright star pass behind the plume of gas and dust that spews from Saturn's icy moon Enceladus.

Saturn's Criss-Crossed Rings

At first glance, Saturn's rings appear to be intersecting themselves in an impossible way.

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.
