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.
The evidence dates back to 1921 when astronomers first observed the complex but unidentified molecules in space. Since then astronomers have ruled out all but organic molecules as the explanation of the data, and independent evidence points to specific classes of carbon-based molecules.
Snow explained that scientists don't know where the molecules came from, but the best bets are that they formed either in the outer layers of red giant stars or through the shattering of carbon dust grains in space. During the show, Snow will show the planetarium audience where the molecules occur in the Milky Way galaxy.
The organic molecules, whatever they are, could be important contributors to the origin of life.
Fiske Planetarium's monthly live shows give the audience a chance to talk to numerous experts from CU-Boulder.
Tickets go on sale at 7 p.m. the night of the show and are $4 for adults and $3 for seniors and children. Fiske Planetarium is located at Regent Drive and Kittredge Loop Drive on the CU-Boulder campus.
