Great Beyond: ALMA Scientists Hope To Unlock Space Secrets

In northern Chile, at 16,500 feet above sea level, scientists from around the world are building the world's largest radio telescope. When completed in 2013, sixty-six huge antennas--some weighing 115 tons--will stretch across a 10 square mile area of desert, point at the stars and try to unlock the secrets of the universe. The research there has already started; Harry Smith takes a rare trip to this remarkable and unearthly place.
