Charles Darwin

Hands-on Darwin
February 16, 2007

One hundred and forty-eight years after the publication of Charles Darwin's On the Origin of Species by Means of Natural Selection, his widely accepted scientific explanation for the evolution of species still stimulates much controversy and heated discussions. What did—and didn't—Darwin say? What have scientists learned about the mechanisms of evolution since the publication of his groundbreaking book?

Join Exploratorium biologist Karen Kalumuck as she leads a Darwin 101 Webcast using hands-on explorations, audience participation, and special surprises.

Science from the Poles 
November 25, December 2, 9, 30, 2006

Listen to a live video chat and meet the cosmologists building the South Pole Telescope, the largest telescope ever deployed there. When completed, the telescope will give astronomers a powerful new tool to explore dark energy, the mysterious force that may be causing the universe to accelerate. In addition, Exploratorium senior scientist Paul Doherty discusses climate change and presents hands-on activities related to the topic.


Transit of Mercury
November 8, 2006
On November 8, 2006, Mercury slowly slid across the face of the sun during an event known as a transit. A transit of Mercury is relatively rare—there are only about a dozen in a century.
The Exploratorium’s Live@ crew was at the Kitt Peak National Observatory, and, with the Kitt Peak staff, we Webcast the transit: a live five-hour telescope-only feed began at 11:00 am PST.

Ancient Writings Revealed!
August 4, 2006
Watch ancient text revealed and read for the first time in a thousand years! Archimedes was one of the world's greatest scientific and mathematical minds. His thoughts were inscribed on goatskin parchment, but the letters and diagrams were scraped off and written over by Greek monks in the Middle Ages. Using an intense x-ray beam generated at Stanford University's linear accelerator, some of the original Greek text was revealed for the first time in the modern world.



Eclipse: Live from Side, Turkey
March 29, 2006
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 will continue moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting.

For the fourth time, Live@Exploratorium and NASA's Sun-Earth Connection travelled into the path of totality to broadcast this momentous event live, in real-time, via satellite and the Web.
