Big Picture Science is a weekly one-hour science magazine that connects ideas in surprising and humorous ways to illuminate the origins and evolution of life and technology on this planet… and beyond.

From free-thinking robots... to the recipe for dark matter... to the mix-and-match genes of synthetic biology, we have it all! One episode a month, Skeptic Check, is devoted to critical thinking.

Produced at the SETI Institute and hosted by Seth Shostak and Molly Bentley.

Big Picture Science can be found on iTunes and other podcast sites. Radio stations carrying the program are listed on our "listening" page at radio.seti.org

The program is freely available to radio stations for broadcast.

The show began with the title Are We Alone? in 2002.
