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.

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.

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.

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.

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.
