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. 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! 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 measures the power used by two lightbulbs--one incandescent and one fluorescent--that make the same amount of light. 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. 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. Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury. 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. On March 29, 2006, a total solar eclipse occurred as the moon moved directly between the earth and the sun. The moon's shadow fell on the earth, first darkening the eastern tip of Brazil, and then moved across the Atlantic Ocean to make landfall in Ghana, Africa. It continued moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting. On December 11, 2005, Opportunity, one of the twin rovers exploring Mars, celebrated its first Martian birthday. Opportunity had been on the red planet 687 Earth days, which is one Martian year. (A year is the time it takes a planet to make a complete loop around the sun). Join us for a look back over the those 687 days of discovery: what we learned, what we saw, and what questions remained unanswered.
