Venus Transit Webcast –

On June 5, 2012, the planet Venus crossed the face of the Sun for the last time until the year 2117. Keck Observatory and the West Hawaii Astronomy Club teamed up to live webcast the entire event from the Keck I Telescope control room near the summit of Mauna Kea on the Big Island of Hawai’i. Here is the entire unabridged webcast, broken into four parts. The original viewership of the live webcast was more than 87,000, with an estimated total audience of more than 120,000.

The W. M. Keck Observatory operates two 10-meter optical/infrared telescopes on the summit of Mauna Kea on the Big Island of Hawaii. The twin telescopes feature a suite of advanced instruments including imagers, multi-object spectrographs, high-resolution spectrographs, integral-field spectroscopy and a world-leading laser guide star adaptive optics system which cancels out much of the interference caused by Earth’s turbulent atmosphere. The Observatory is a private 501(c) 3 non-profit organization and a scientific partnership of the California Institute of Technology, the University of California and NASA.
