Founded in 1918, the Observatory brings together students, staff, faculty, engineers, and technicians to explore the universe and share discoveries through world-class research, education, and outreach. With more than 180 professionals supporting advanced facilities, laboratories, and observatories, Steward Observatory offers a collaborative environment where technical expertise plays a critical role in advancing ground- and space-based astronomy.
