"You have to remember this is an artwork, not a scientific work....It's really about feeling your connection with the space and the stars and these different alignments." Charles Ross

How and why do humans look at the sky, stars, and sun, and how do we try to make sense of what we see? On a small mesa in northern New Mexico where the Sangre de Cristo Mountains meet the eastern plains, 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. In November 2003, Exploratorium staff members visited Charles Ross's work-in-progress, Star Axis. We explored our perceptions of time, how time relates to celestial activity, and our connection to exploring the heavens.
