Rife with Life — “Follow the water” is the mantra of those who search for life beyond Earth. Where there’s water, there may be life. Join us on a tour of watery solar system bodies that hold promise for biology. Dig beneath the icy shell of Jupiter’s moon Europa, and plunge into the jets of Enceladus, Saturn’s satellite. And let’s not forget the Red Planet. Mars is rusty and dusty, but it wasn’t always a world of dry dunes. Did life once thrive here? Also, the promise of life in the exotic hydrocarbon lakes of Titan. Science-fiction author Robert J. Sawyer joins us, and relates how these exotic outposts have prompted imaginative stories of alien life.

How SETI Works — SETI stands for ‘search for extraterrestrial intelligence,’ and the term is used to describe both the SETI institute and the search for alien life in general. In this spaced-out episode, Josh and Chuck explore the origin, aims and challenges facing SETI.
"Someone described my office as an eight-year-old’s daydream," says astronomer Jill Tarter, who has been collecting E.T.-themed office ornaments for 30 years. Tarter was the SETI (Search for Extraterrestrial Intelligence) Institute’s first employee, and the inspiration for the character in Carl Sagan’s Contact.
