University of Minnesota astrophysicist Robert Schwarz holds the record for spending the most number of winters--14--at the South Pole.

Some highlights of a South Pole winter: six months of darkness, sub-zero temperatures, and no flights, in or out, from February to October.

Schwarz works with Professor Clem Pryke, watching over the Keck Array, a cluster of microwave telescopes at the geographic South Pole. The Keck Array observes the echoes of the Big Bang embedded in the oldest light in the universe, the Cosmic Microwave Background.
