A new study finds that the mysterious equatorial dune patterns on Saturnâ€™s largest moon, Titan, are the result of gusty winds blowing in the opposite direction of prevailing weather.
Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan.
U.S. scientists have developed an alternate theory for the origin of linear dunes on the surface of Titan, Saturn's largest moon, similar to ones on Earth. Louisiana State University Professor Patrick Hesp and U.S.
The paper, "Multiple origins of linear dunes on Earth and Titan," examines a possible new mechanism for the development of very large linear dunes formed on the surface of Titan, Saturn's largest moon.
"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August.

Titan's vast dune fields, which may act like weather vanes to determine general wind direction on Saturn's biggest moon, have been mapped by scientists who compiled four years of radar data collected by the Cassini spacecraft.
Data collected during several recent flybys of Titan by NASA's Cassini spacecraft have put another arrow in the quiver of scientists who think the Saturnian moon contains active cryovolcanoes spewing a super-chilled liquid into its atmosphere.
Dr. Rusty Feagin was managing several ecosystem research projects on Galveston Island when the 2008 hurricane season began.Then he got an unexpected visit from a research assistant named Ike."Ike reconfirmed the basic idea I've had for several years," said Feagin, ecosystem scientist with Texas AgriLife Research. "The plants on sand dunes and in marshes build an island's elevation, so we shouldn't compromise that."Most of the dunes and marshes he and his graduate students had studied were...
Scientists have confirmed that at least one body in our solar system, other than Earth, has a surface liquid lake.
