In the shadow of the Moon

Copyright ExploratoriumAs the Moon’s shadow fell over the Xinjiang Province in northwestern China today, an eclipse expedition team from the Exploratorium, the center’s fifth since 1998, stood ready to webcast the total solar eclipse live to the world. Four cutting-edge telescopes were used to provide live feeds of the eclipse, and Exporatorium scientists Rob Semper and Paul Doherty provided commentary on prominences, sunspots, and the corona as they occured.

Back in San Francisco, visitors were invited to an overnight viewing party with solar science activities and traditional Chinese performances leading up to the live broadcast at 3:30 a.m. local time. A virtual viewing party, complete with interactive exhibits and music, was held on Exploratorium Island in Second Life.
