8 PM - Lecture

Larger than the planet Mercury, Saturn's moon Titan is a world all its own. Hidden by a murky atmosphere, the details of the moon's surface have long been a mystery. The Cassini-Huygens mission has explored Titan with more than 20 close flybys and a probe to the moon's surface, revealing an intriguing terrain that is both familiar and alien. Tantalizing evidence exists, primarily in the form of channels and ponds or lakes, that liquids have flowed on the surface and may continue to be present. Elizabeth P. Turtle will describe the latest observations and present the current understanding of this strange world.

Elizabeth P. Turtle is a Planetary Scientist at the Johns Hopkins University Applied Physics Lab, and a member of the Cassini Imaging Team.

This lecture is free, but tickets are required.

The 2007 Exploring Space Lectures, Journey Through the Outer Solar System, will feature four world-class scholars discussing current missions to the distant realm of the gas giants, the icy Kuiper Belt, and beyond.
