Are we alone in the universe? That’s the billion-dollar-question that has fascinated humans for centuries. In "Five Billion Years of Solitude: The Search for Life Beyond the Stars," journalist Lee Billings traces the history of scientific research into space and the universe as he attempts to explain human obsession with the possibility of life beyond Earth. Billings is joined by Peter McCullough, associate astronomer at the Space Telescope Science Institute, which operates the Hubble Telescope for NASA. Original air date 01/17/14
