Methane rain "on the rocks"...
space, astrophysics, researchToo cool. We have weather, houston (from "Titan's Streams Like Earth's"):
Many of the same processes that helped shape the Earth are in effect today on Saturn's smoggy moon Titan, a team of international scientists revealed on Friday. [See: "Seeing, touching and smelling the extraordinarily Earth-like world of Titan" and "Islands, rivers and methane springs - latest images of Titan".]
Relying on data gathered directly from the atmosphere and surface of Titan last week by the European Space Agency's Huygens space probe, the scientists said they were able to conclude that a regular pattern of precipitation and erosion is carving out streambeds and leaving behind a layer of "dirt" on the giant moon.
"There is liquid that is flowing on the surface of Titan," said planetary scientist Toby Owen,of the Institute for Astronomy, during an ESA-sponsored press conference. "It's not water -- it's too cold -- but liquid methane. And it flows in the same way it does on Earth."
