Mt. Lemmon SkyCenter offers a unique set of programs. Our anchor program is SkyNights, a public observing program that is open most nights of year using the Southwest's largest dedicated public telescope! During summer months our facility hosts day-time programs that explore the biology, ecology, geology of this unique sky island—and provide a cool spot away from the desert heat. Our programs highlight the unique aspects of the sky island and observatory but also work with our partners in UA Science.
