Steward Observatory





The observatory of the University of Arizona, which, together with the Department of Astronomy, form one of the largest academic centers of astronomical studies in the world. Established in 1916 by its first director, Andrew Ellicott Douglass and a bequest made by Lavinia Steward in memory of her late husband, the Steward Observatory now owns and operates the Multiple Mirror Telescope and Mount Graham International Observatory, and also operates a number of other major optical and submillimeter telescopes at several sites in the state. The Steward Observatory Mirror Laboratory has pioneered new techniques of large mirror production, including spin-casting and honeycomb mirrors, while the Center for Astronomical Adaptive Optics is at the forefront of developments in adaptive optics. Recent and current construction projects within the Observatory have included making the mirrors for the Magellan Telescopes and the Large Binocular Telescope.
