| This month’s speaker will be Dr. Taylor Perron of the MIT Department of Earth, Atmospheric and Planetary Sciences whose research focuses on the physical processes that create landscapes, both on earth and on other planets and moons. He will be speaking to us about Saturn’s moon Titan which is only one of three bodies (the others being Earth and Mars) in the solar system where rivers of liquids have carved branching networks of valleys into the surface. Unlike those on Mars, Titans rivers have been known for less than a decade, and they may be currently active. Unlike rivers on Earth and Mars, Titan’s landscapes have been carved into water ice by liquid hydrocarbons. Despite this exotic combination of materials, Titans river networks look strikingly similar to Earth’s. Dr. Perron will describe his group’s efforts to understand how Titan’s rivers have shaped its landscape, and how that landscape can constrain rates of methane rainfall, which have not been measured directly.
Please join us for a pre-meeting dinner discussion at Changsho, 1712 Mass Ave, Cambridge, MA at 6:00pm before the meeting. |
