Saturn's Southern Hemisphere

Winter is approaching in the southern hemisphere of Saturn and with this cold season has come the familiar blue hue that was present in the northern winter hemisphere at the start of NASA's Cassini mission.

Titan's Halo

NASA's Cassini spacecraft looks towards the dark side of Saturn's largest moon, Titan, capturing the blue halo caused by a haze layer that hovers high in the moon's atmosphere.

The Yin and Yang Appearance of Iapetus

Iapetus is a moon of extreme contrasts. The light and dark features give the moon a distinctive "yin and yang" appearance.

Cassini is providing scientists with key clues about Saturn's moon Titan, and in particular, its hydrocarbon lakes and seas.

NASA has released a natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible.

Melanthius Crater on Tethys at Dusk

The craters of Tethys tell the story of a violent history marked by impacts. The names of the craters also tell oft-violent stories: in this case, the Iliad and the Odyssey.

Quintet of Saturn's Moons

This view, from 29 July 2011, looks toward the northern, sunlit side of the rings from just above the ringplane.

New Views of Titan's Land of Lakes

With the sun now shining down over the north pole of Saturn's moon Titan, a little luck with the weather, and trajectories that put the spacecraft into optimal viewing positions, NASA's Cassini spacecraft has obtained new pictures of the liquid methane and ethane seas and lakes that reside near Titan's north pole.

The NASA-ESA-ASI Cassini spacecraft has been observing the Saturn system, including the giant satellite Titan, for more than 9 years. A detailed analysis of Cassini data has now confirmed predictions that the density of Titan's ionosphere is directly linked to the 11 year cycle of solar activity.

Stunning View From High Above Saturn

This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013.

Recent work by planetary scientists has indicated that the deep atmospheres of Jupiter and Saturn may contain chunks of diamond floating in a liquid hydrogen/helium fluid.

People around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA's Cassini mission on July 19 -- the day the Cassini spacecraft turned back toward Earth to take our picture.

Saturn's Epimetheus, Going Rogue?

Although Epimetheus appears to be orbiting between the A and F rings in this image, it's just an illusion! Epimetheus, which orbits Saturn well outside of the F ring's orbit, is actually on the near side of Saturn to Cassini while the rings seen here are on the far side of the planet. Whew, that's a relief!

Saturn Propeller, Light and Dark

The Cassini spacecraft has been monitoring propeller features since their discovery. Here the propeller dubbed Bleriot is seen in a recent image. The bright dash-like features are regions where a small moonlet has caused ring particles to cluster together more densely than normal.

Hints of Activity on Dione

From a distance, most of the Saturnian moon Dione resembles a bland cue ball. Thanks to close-up images of a 500-mile-long (800-kilometer-long) mountain on the moon from NASA's Cassini spacecraft, scientists have found more evidence for the idea that Dione was likely active in the past. It could still be active now.

Scientists have created the first global topographic map of Saturn's moon Titan, giving researchers a valuable tool for learning more about one of the most Earth-like and interesting worlds in the solar system. The map was just published as part of a paper in the journal Icarus.

As planets age they become darker and cooler. Saturn, however, is much brighter than expected for a planet of its age -- a question that has puzzled scientists since the late sixties.

NASA's Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole.

Map of Enceladus' South Pole

The northern and southern hemispheres of Enceladus are seen in these polar stereographic maps, mosaicked from the best-available Cassini clear-filter images.

Titan's Methane: Soon To Be Gone?

By tracking a part of the surface of Saturn's moon Titan over several years, NASA's Cassini mission has found a remarkable longevity to the hydrocarbon lakes on the moon's surface.
