This colorized flyover movie from NASA's Cassini mission takes viewers over the two largest seas on Saturn's moon Titan and nearby lakes.

This video describes a computer model that proposes a flow vortex in Saturn's upper atmosphere or ionosphere can explain periodic signatures observed by NASA's Cassini spacecraft in Saturn's magnet...

Great Red Spot

Part of the shadow of Saturn's moon Mimas appears as if it has been woven through the planet's rings in this unusual series of images from Cassini.

NASA's Cassini spacecraft discovered hydrogen in the plume of gas and icy particles spraying from Saturn's moon Enceladus. The discovery means the small, icy moon — which has a global ocean under i...

Atlas Found!

This computer-generated animation shows all of Cassini's orbits - affectionaly called the "ball of yarn" by mission planners.

Ceres' lack of giant impact basins presents a puzzle to scientists.

This movie uses data from NASA's Dawn spacecraft to simulate the view from the spacecraft flying over the surface of the giant asteroid Vesta.

The flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. 

Big water news from Saturn's tiny moon Enceladus.

NASA’s Cassini mission will come to a spectacular close on September 15, 2017 after almost two decades in space since its launch in 1997.

This graphic shows in a series of three images how Saturn's rings, after they became tilted relative to Saturn's equatorial plane, would have transformed into a corrugated ring.

This computer-generated view shows the view from the perspective of the Cassini spacecraft as it dives between the rings and Saturn's cloud tops.

Annette and Alden Tombaugh, the children of Clyde Tombaugh, remember their father and his discovery of Pluto.

Hello from Saturn, essentially on the opposite side of the sun as seen from Earth! This annual occurrence called solar conjunction, when Saturn (and Cassini) nearly disappear behind the sun.

Cassini mission planners created this animation to showcase Cassini's final 22 orbits - the mission's Grand Finale.

A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.

The Usual Suspects: Science research is like detective work. One scientist takes his case to California's Death Valley, to search for clues surrounding a Titan lake.

A large sunspot was the source of a powerful solar flare and a coronal mass ejection (Sept. 6, 2017). The flare was the largest solar flare of the last decade. For one thing, it created a strong sh...

The moon Tethys is joined by two smaller moons in this movie from NASA's Cassini spacecraft.

The Cassini spacecraft arrived at Saturn in June 2004 and is now halfway through its mission. A new photo essay showcases some stunning images returned by the mission.

Filters, pixels and math star in this narrated cartoon.

JPL's Dawn mission is en route to rendezvous with the main-belt asteroids Vesta and Ceres, and is using ion propulsion to get there.
