Organic compounds that come from outer space in meteorites are probably relics of a primordial gas phase, conclude Martin Studier (Argonne National Laboratory), Ryoichi Hayatsu, and Edward Anders (both of the University of Chicago). Moreover the gas phase was probably the solar nebula, and during planetary evolution the organics were probably formed under conditions of thermodynamic equilibrium. Thus the idea that such substances indicate extraterrestrial biology, already abandoned by most scientists, is further discredited.
