Watch as three giant helium balloons are launched above Antarctica to study climate history; listen as scientists talk about balloon research. Learn about the various projects and teams of people working on the South Pole Telescope. What is dark energy? Cosmologist Rocky Kolb explains how the South Pole Telescope will help us understand the properties and nature of this mysterious force. A year and a half after entering Saturn's orbit, the Cassini spacecraft continued to gather exciting new information. Dr. Paul Doherty and Dr. Eric Weygren bring us up to date on the Cassini Mission and show stunning images of Saturn and its ever-growing assortment of moons. Join us as we talk with Jill Tarter, Director of the Center for SETI Research and the inspiration behind Jody Foster's character in the movie Contact. Find out about the tools and technologies being developed for a multigenerational effort to search for life on other planets. James Turrell studied optics and perceptual psychology in college, but gravitated towards art as his curiosity led him to investigate light itself. In this Webcast of a lecture, James Turrell discusses his experiences manipulating pure light and how it became his artistic medium. He reveals how this early work led him to discover Roden Crater in Arizona and to create his subsequent lifelong project of transforming the crater into an astronomical observatory.
