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.
