Researchers build alien ocean to test NASA outer space submarine

Building a submarine gets tricky when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane. Researchers are working to determine how a submarine might work on Titan, the largest of Saturn's many moons and the second largest in the solar system. The space agency plans to launch a real submarine into Titan seas in the next 20 years.

Saturn's moon Titan sports Earth-like features

Using the now-complete Cassini data set, astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain.

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.
