E.T. Might Prefer a Letter

We check in with the progress of search for extraterrestrial intelligence. A paper published this week in the journal Nature argues that for sending lots of data over long distances, it's hard to beat sending a physical artifact engraved with data. We'll talk about ways to communicate lots of information over long distances.

Guests:

Dan Werthimer, chief scientist, SETI@home. SERENDIP (Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations) project director, Space Sciences Laboratory at the University of California, Berkeley.
