Finding the fundamental building blocks of life in outer space will be the topic of "Organic Molecules in Space," a live show at the University of Colorado at Boulder's Fiske Planetarium on Friday, March 2, and Tuesday, March 6, at 7:30 p.m. Astrophysical and planetary sciences Professor Theodore Snow will present evidence that large organic (carbon-based) molecules are common in space. "There is a lot of speculation as to what the molecules are, but precious little definitive identification," Snow said.
