About

A small group of explorers stands beneath an open dome of night sky as pinpricks of starlight glitter against the expanse's dark blues and blacks. Each spot of light even seems to look much clearer from here—likely because the group is standing 9,157 feet above sea level. At the Stewart Observatory inside Mt. Lemmon SkyCenter at the mountain's summit, scientists guide visitors through the use of gear such as a 32-inch Schulman telescope—the state's largest public viewing telescope—to probe the far reaches of space to learn about celestial phenomena and take in magnified images of the universe just above.

Days and nights at the center bring a slew of learning experiences to budding astronomers. Accompanied by University of Arizona scientists, Discovery Days lead explorations of topics such as tree rings, hummingbirds, and meteorology, frequently beckoning students into the surrounding outdoors. During nightly SkyNights programming, groups summit Mt. Lemmon for a five-hour evening of dining and stargazing at the observatory. One-on-one time with heavenly bodies comes courtesy of Astronomer Nights, wherein site staffers grant singles or pairs lodging, private access to the Schulman telescope, and the chance to contribute directly to the field upon discovering a supernova, nebula, or handlebar mustache on the man in the moon.

Periodically, the scientific team also expounds on specific topics, such as digital celestial imaging, with the public in multiple-day workshops. Each participant builds on the Stewart Observatory's list of achievements since 1970, which include furthering infrared astronomy, surveying the moon for Apollo lunar landings, and searching for near-Earth asteroids.
