The South Pole Telescope captured its first light on Feb. 16, 2007! Join Exploratorium host Mary Miller as she talks with scientists at the South Pole and finds out more about life at the Pole. Join Exploratorium biologist Karen Kalumuck as she leads a Darwin 101 Webcast using hands-on explorations, audience participation, and special surprises—just in time to celebrate his birthday! Mary Miller chats with scientists at the South Pole about the nearly-completed telescope. The satellite connection to the pole deteriorated quickly, and we hope to repeat this program in the near future. Stay tuned for updates! Dr. Stephen H. Schneider joins us to discuss climate change. Dr. Schneider was honored in 1992 with a MacArthur Fellowship for his ability to integrate and interpret the results of global climate research through public lectures, seminars, classroom teaching, and research collaboration with colleagues. Join us as we talk to South Pole scientists about Ice Cube, a major new telescope being built deep below the surface to detect ghostly neutrino particles. The neutrino telescope will use thousands of detectors spread over a square kilometer of ice below the South Pole to study cosmological mysteries such as black holes, gamma ray bursts, and the remnants of supernova explosions.
What's Christmas like at the South Pole? Also learn about the Race Around the World and the installation of the telescope's new receiver. Join Senior Scientist Paul Doherty as he explains the difference between floating ice and land ice, and why they effect sea levels differently. Join Senior Scientist Paul Doherty as he measures the power used by two lightbulbs--one incandescent and one fluorescent--that make the same amount of light. Join Senior Scientist Paul Doherty as shows how to melt ice unbelievably fast! Join Exploratorium staff as they give the quick answers to the most frequently asked questions about global warming: What is a "tipping point"? What are carbon credits? What is carbon neutral? What can I do? What can my kid do?
