Ancient Observatories: Chaco Canyon
Live from the Exploratorium

December 21, 2004 @ 12 Noon Pacific Standard Time

Join the Live@ crew and NASA scientists as we delve into the ancient knowledge of the Chacoans, daily sky watchers who amassed a great knowledge about the movements of the sun. Find out what they knew, and how they used this knowledge to create sophisticated monuments to the sun. Today, astronomers and solar physicists continue to watch the sun using modern ground-based observatories and orbiting space telescopes. Learn why this work is important, and why solar research is still so vital.
