Are We Alone - Off to the Traces

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.
