Light and Landscape: Charles Ross and Star Axis (Webcast)
Running Time:
00:10:19
00:10:19
Join the Exploratorium's Dr. Paul Doherty as he visits a "sculpture to observe the stars" in northern New Mexico, where the Sangre de Cristo Mountains meet the eastern plains. There artist Charles Ross is creating an art installation that is also a star observatory. This major earthwork has two main elements: the Star Tunnel, which allows you to walk through the entire history of the earth's changing alignment to our North Star, Polaris; and the Solar Pyramid, where one can visually experience an hour of the earth's rotation.
