First hour guests Seth Shostak and Laurance Doyle, both of SETI(1), discussed the hypothetical alien worlds that are presented in the upcoming National Geographic special, Extraterrestrial(2). For instance, on the planet "Aurelia," fields of "stinger fans"-animals that look like tall plants- might turn towards the light of the red dwarf in the sky (pictured). What Shostak particularly liked about the program, was that it imagined aliens as they really might be, rather than how they are more typically depicted. More Info(3)/View Media/Seth's Blog
