Southern SETI Director Guillermo Lemarchand describes from Buenos Aires why his search for extraterrestrial intelligence is uniquely exciting. Emily Lakdawalla sheds light on how spacecraft take pictures in the darkness of the outer solar system. Bruce Betts tells Mat Kaplan about the night sky and digs up the derivation of the mineral Armalcolite, winning a Planetary Radio t-shirt for a listener. He also announces a new space trivia contest.
