With so much attention given to one problematic study this week, astrobiology is getting an awful lot of attention--and probably not the sort that astrobiologists would like. If you want to broaden your view of this intriguing area of research, get thee to Itunes! Lynn Rothschild teaches a class on astrobiology at Stanford, and the winter 2010 edition of the course is available FOR FREE on Itunes. (I just started watching a couple classes and then decided to download the whole thing.) Also, check out the snazzy class web site for more on the study of life in the universe.
