Hunting the Edge of Space: The Mystery of the Milky Way
Tuesday, April 6 at 8:00 p.m. on WPBT2
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. This tale of human ingenuity involves some of the most colorful figures of the scientific world — Galileo, Kepler, Newton, William Herschel, George Hale and Edwin Hubble — leading up to today’s colossal telescopes, housed in space-age cathedrals or orbiting high above the Earth. Now, at the center of an international space race, a new generation of ever-larger telescopes is poised to reveal answers to longstanding questions about our universe — and, in turn, to raise new questions.

Now, modern telescopes have added a mysterious new twist to the plot: The vast majority of the stuff of the universe is invisible, tied up in dark matter and dark energy. But what are these mysterious dark forces? A new generation of telescopes is embarking on a mission impossible to see the unseeable and answer one of the greatest unsolved mysteries of the cosmos.
