Electrical and chemical coupling between Saturn and its rings

A Langmuir probe, flown to Saturn on the Cassini spacecraft, has made exciting discoveries in the atmosphere of the planet. They discovered that there is a strong coupling, both chemically and electrically, between the atmosphere of Saturn and its rings.

Frictional heat powers hydrothermal activity on Enceladus

A computer simulation shows how icy moon heats water in a porous rock core. This study also offers among others an answer to the long-standing question of where the energy that can support water in liquid form on a small, cryovulcanic moon far from the sun comes from.

Unexpected atmospheric vortex behavior on Saturn's moon Titan

Recently reported unexpected behavior on Titan, the largest moon of Saturn, is due to its unique atmospheric chemistry. Titan is the largest moon of Saturn, is bigger than the planet Mercury, and is the only moon in our solar system to have a substantial atmosphere.

Noxious ice cloud on Saturn's moon Titan

Researchers with NASA's Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn's largest moon, Titan.

To keep Saturn's A ring contained, its moons stand united

For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring -- the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, astronomers now conclude that the teamwork of seven moons keeps this ring corralled.

Intense storms batter Saturn’s largest moon, scientists report

Titan, the largest of Saturn's more than 60 moons, has surprisingly intense rainstorms, according to research by a team of UCLA planetary scientists and geologists. Although the storms are relatively rare -- they occur less than once per Titan year, which is 29 and a half Earth years -- they occur much more frequently than the scientists expected.

Reconstructing Cassini's plunge into Saturn

As NASA's Cassini spacecraft made its fateful dive into the upper atmosphere of Saturn on Sept. 15, the spacecraft was live-streaming data from eight of its science instruments, along with readings from a variety of engineering systems. While analysis of science data from the final plunge will take some time, Cassini engineers already have a pretty clear understanding of how the spacecraft itself behaved as it went in.

The strange structures of the Saturn nebula

The spectacular planetary nebula NGC 7009, or the Saturn Nebula, emerges from the darkness like a series of oddly-shaped bubbles, lit up in glorious pinks and blues. This colourful image was captured by the MUSE instrument on ESO's Very Large Telescope (VLT). The map -- which reveals a wealth of intricate structures in the dust, including shells, a halo and a curious wave-like feature -- will help astronomers understand how planetary nebulae develop their strange shapes and symmetries.

NASA's Cassini spacecraft ends its historic exploration of Saturn

A thrilling epoch in the exploration of our solar system has come to a close, as NASA's Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet. Cassini's plunge brings to a close a series of 22 dives between Saturn and its rings, a feat never before attempted by any spacecraft.
