Spent the past week here in Manizales, Colombia, with Jorge Bueno, the very impressive director of the Colombia Instituto de Astrobiologia. Gave a couple of talks at Univ of Caldas (nice place!), got interviewed about astrobiology on local TV (live! in Spanish!), and visited the volcano twice with various students and scientists. The clouds behind me is the volcano emitting ash and the hot spring has temperature of 70° C and pH of 1.3. There are very good research possibilities up there.
