Dark Sky International is a non-profit whose mission is to protect night viewing for humans and wildlife by battling light pollution. Tucson has been a Dark Sky city since 2018 when they passed city ordinances that took steps to minimize city glow. All outdoor lights in Tucson have to be adjustable LED lights that are shielded, so that light is focused downward. This ensures that the world famous Kitt Observatory on Kitt Peak, Mt. Lemmon SkyCenter, and Steward Observatory at the University of Arizona all have ample darkness to do their work. It also provides Tucson residents, and visiting Ingress Agents with some of the best stargazing opportunities, an incredible feat for a city of Tucson’s size.
