Discover more about Steward Observatory (University of Arizona)

Steward Observatory, the research arm of the University of Arizona's Department of Astronomy, stands as one of the world's leading centers for astronomical studies. Founded in 1916, its establishment was made possible through the generosity of Lavinia Steward, who bequeathed funds in memory of her late husband, Henry B. Steward. The observatory's first telescope was formally dedicated in 1923. The original observatory building, a stately structure with a cream-colored tile dome, is a campus landmark listed on the National Register of Historic Places. While the original 36-inch Newtonian telescope was relocated to Kitt Peak in 1963 due to Tucson's urban expansion, a smaller 20-inch Cassegrain telescope remains for student use. Today, Steward Observatory continues to be at the forefront of astronomical research and technology. Its astronomers are leaders in observational and theoretical research, making breakthroughs in areas like new light detectors and giant telescope mirrors. The Richard F. Caris Mirror Laboratory, located beneath the Arizona Stadium, is a testament to this innovation, pioneering techniques in large mirror production. Steward Observatory scientists also play key roles in major space missions, including the Hubble Space Telescope. Visitors can explore exhibits on the University of Arizona campus and learn about the various space missions supported by NASA. Every other Monday, the observatory opens its dome for public viewing of the moon, planets, nebulae, and galaxies.
