Presenter: Seth Shostak, SETI Institute
When: October 25, 2010 1PM PDT

If a tree fell on another planet, would we be able to detect it? Not quite yet – but we might be able to tell if the planet was habitable. A living-planet is the promise of newly-discovered Gliese 581g. But does the planet exist at all?

Discover how we learn a planet’s geology and chemistry from afar. Also, what we learn about a civilization from what it discards, beginning with our own sloppy habits.

Plus, the hunt for derelict alien spaceships… and a man who sketches alien creatures for a living – based on real science.

Big Picture Science

  • The Big Picture Science radio show and podcast engages the public with astrobiology through lively and intelligent storytelling. Science radio doesn’t have to be dull. The only dry thing about our program is the humor. Big Picture Science takes on big questions by interviewing leading researchers and weaving together their stories of discovery in a clever and off-kilter narrative style.
