92 | Kevin Hand on Life Elsewhere in the Solar System

It's hard doing science when you only have one data point, especially when that data point is subject to an enormous selection bias. That's the situation faced by people studying the nature and prevalence of life in the universe. The only biosphere we know about is our own, and our knowing anything at all is predicated on its existence, so it's unclear how much it can teach us about the bigger picture. That's why it's so important to search for life elsewhere. Today's guest is Kevin Hand, a planetary scientist and astrobiologist who knows as much as anyone about the prospects for finding life right in our planetary backyard, on moons and planets in the Solar System. We talk about how life comes to be, and reasons why it might be lurking on Europa, Titan, or elsewhere.

Kevin Hand received his Ph.D. in Geological and Environmental Sciences from Stanford University. He is currently Deputy Chief Scientist for Solar System Exploration at NASA's Jet Propulsion Laboratory. He has collaborated with director James Cameron, and is a frequent consultant on films, including acting as a science advisor to the movie Europa Report. His a cofounder of Cosmos Education, a non-profit organization devoted to science education in developing countries. His new book is Alien Oceans: The Search for Life in the Depths of Space.

It's pretty clear that our genes affect, though they don't completely determine, who we grow up to be; children's physical and mental characteristics are not completely unrelated to those of their par...

How human beings behave is, for fairly evident reasons, a topic of intense interest to human beings. And yet, not only is there much we don't understand about human behavior, different academic discip...

Physics is extremely good at describing simple systems with relatively few moving parts. Sadly, the world is not like that; many phenomena of interest are complex, with multiple interacting parts and ...

There is no general theory of problem-solving, or even a reliable set of principles that will usually work. It's therefore interesting to see how our brains actually go about solving problems. Here's ...
