Antarctica w/ Christine Corbett Moran

Cara connects with an astrophysicist who's working in the most remote place on Earth: Dr. Christine Corbett Moran talks nerdy from the Amundsen-Scott South Pole Station, deep in the heart of Antarctica. They discuss the challenges and privileges of spending a cold, dark winter at the geographic South Pole, including stunning auroras and joining the 300 club. Follow Christine: @corbett.
