Southern Arizona's clear, dark skies have made Tucson an important center for Astronomy. Because of light pollution, the skies aren't as dark as they once were, but there is still plenty to offer to astronomy buffs. On the Tohono O'odham Nation fifty-five miles southwest of Tucson on a peak in the Quinlan Mountains sits Kitt Peak National Observatory. Here, is the world's largest collection of optical telescopes. There are daytime tours and nighttime programs that allow viewing through a 20-inch telescope.
