A brief overview of the topics we will cover in\nAstronomy 141, setting the stage for how we can make a serious\nscientific inquiry out of the question of whether or not there is life\nelsewhere in the Universe. It is a short lecture, the first half was an\noverview of course mechanics (tests, homework, office hours, etc.) that\nI did not record. Recorded live on 2009 Sep 23 in Room 1005 Smith\nLaboratory on the Columbus campus of The Ohio State University.
