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.

00:15:00
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!

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.

Check out this amazing footage of how scientists drop detectors miles into the ice to search for elusive neutrinos.

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.

00:28:51
Tom Crawford and Jeff McMahon show us a day in the life of a South Pole scientist, then talk about what the telescope will be searching for: dark matter, galaxy clusters, and evidence of the universe expanding.

00:28:45
South Pole scientists Tom Crawford and Jeff McMahon take us on a virtual tour of the South Pole Station, then discuss working in the polar environment.

00:34:45
After years of preparation, scientists from the University of Chicago are making the long journey to the South Pole to begin construction on the new 10-meter telescope. Join us as we talk to scientists at the pole about their long journey, learn about the pre-building of the telescope in Texas last summer; and find out what challenges they face in constructing a major scientific instrument in freezing conditions.

Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury.

05:12:09
On November 8, 2006, Mercury slowly slid across the face of the sun during a relatively rare event known as a transit. The Exploratorium's Live@ crew was at the Kitt Peak National Observatory in Arizona to cover the event. This webcast includes a brief history of Kitt Peak and its 21 telescopes.
