Hunting the Edge of Space, part 2: The Ever Expanding Universe

In this two-hour special, NOVA examines how a simple instrument, the telescope, has fundamentally changed our understanding of our place in the universe. What began as a curiosity—two spectacle lenses held a foot apart—ultimately revolutionized human thought across science, philosophy, and religion. "Hunting the Edge of Space" takes viewers on a global adventure of discovery, dramatizing the innovations in technology and the achievements in science that have marked the rich history of the telescope.

Hour 2, "The Ever-Expanding Universe," introduces a new generation of ever-larger telescopes that is poised to reveal answers to longstanding questions about our universe—and, in turn, to raise new questions.
