How can we search for extraterrestrial intelligence, and what are we

looking for? This second part of a 2-part lecture picks up where we

left off yesterday by examining SETI, the Search for ExtraTerrestrial

Intelligence, and reviews what we might look for and how. We will use

this as a point of departure to then briefly review where we have come

and what we have learned in Astronomy 162, bringing this course to a

close for Winter Quarter 2006. Recorded 2006 Mar 10 in 1008 Evans

Laboratory on the Columbus campus of The Ohio State University.
