Outline of an Ancient Sea on Titan

This image from NASA's Cassini spacecraft shows an ancient southern sea that used to sprawl out near the south pole of Saturn's moon Titan. In an annotated version, the red outline traces the ancient ...

Titan's Hot Cross Bun

NASA's Cassini spacecraft obtained this image of a feature shaped like a hot cross bun in the northern region of Titan (left) that bears a striking resemblance to a similar feature on Venus (right). T...

Ever-Changing Ring

The Cassini spacecraft captures Saturn's ever-changing F ring, showing its bright core, another strand of ring material, and a breakaway clump of material close to the core.

The F ring co...

Angling Saturn

The Cassini spacecraft takes an angled view toward Saturn, showing the southern reaches of the planet with the rings on a dramatic diagonal.

North on Saturn is up and rotated 16 degrees t...

Peeping Mimas

Saturn's moon Mimas peeps out from behind the larger moon Dione in this view from the Cassini spacecraft.

Mimas (246 miles, or 396 kilometers across) is near the bottom center of the imag...

True Colors, Deceptive Sizes

Saturn's largest moon, Titan, appears deceptively small paired here with Dione, Saturn's third-largest moon, in this view from Cassini.

Titan (3200 miles, 5150 kilometers across) is much ...

Enormous Saturn

Compared to the gas giant, the two moons shown on either side of Saturn seem particularly small in this Cassini spacecraft view.

Tethys (660 miles, or 1,062 kilometers across) is on the r...

Titan's Giant North Pole Cloud

Strong Jet in False Colors

A particularly strong jet stream churns through Saturn's northern hemisphere in this false-color view from NASA's Cassini spacecraft.

Clouds associated with the jet stream can be seen in ...

Eddy-Powered Jet Stream

This figure examines a particularly strong jet stream and the eddies that drive it through the atmosphere of Saturn's northern hemisphere. Data from NASA's Cassini spacecraft were used to create this ...

Epimetheus Beyond Rings

The Cassini spacecraft watches Saturn's small moon Epimetheus orbiting beyond the planet's rings.

Line of Craters

The Cassini spacecraft takes a close look at a row of craters on Saturn's moon Tethys during the spacecraft's April 14, 2012, flyby of the moon.

Three large craters are visible along the ...

Serene Scene

Even in a peaceful looking scene such as this one of Saturn and its moon Tethys, the Cassini spacecraft reveals clues about how Saturn is ever-changing. Saturn's northern hemisphere still shows the sc...

Ring Moons' Effects

Saturn's moons Daphnis and Pan demonstrate their effects on the planet's rings in this view from the Cassini spacecraft.

Daphnis (5 miles, or 8 kilometers across), on the left of the imag...

Janus' Craters

Shadows darken parts of some of Janus' large craters as Cassini takes a close look during its flyby of this Saturnian moon on March 27, 2012. See › View Image

Moon Specks

A pair of Saturn's many moons joins the planet in this Cassini spacecraft scene.

Tethys (660 miles, or 1,062 kilometers across) appears as a small white dot above the rings on the far lef...

Bombarded Rhea

Cassini looks over the heavily cratered surface of Rhea during the spacecraft's flyby of the moon on March 10, 2012.

See PIA089...

The Tale Continues...

The brightly reflective moon Enceladus appears before Saturn's rings while the larger moon Titan looms in the distance.

Jets of water ice and vapor emanating from the south pole of Encela...

Smudge of a Shadow

The shadow of the moon Mimas creates a smudge on the southern hemisphere of Saturn in this view from the Cassini spacecraft.

Mimas does not appear here, but it does cast its shadow on the...

Hazy Orange Orb

Titan's atmosphere makes Saturn's largest moon look like a fuzzy orange ball in this natural color view from the Cassini spacecraft.

Titan's north polar hood is visible at the top of the ...
