Scientists are building the world's most advanced radio telescope in Chile's Atacama Desert on a plateau halfway between Earth and space.  In this preview video, Rock Center correspondent Harry Smith journeys to Chile to see the ALMA observatory, which looks straight out of Star Wars and has an ambitious goal: to unlock the secrets of the universe.

Harry Smith's full report, 'Great Beyond,' airs Thursday, July 5 at 10pm/9c on NBC's Rock Center with Brian Williams.
