Revolutionizing Our Knowledge of the Universe

Giant Magellan Telescope is the work of the GMTO Corporation, a 501(c)(3) nonprofit and international research consortium headquartered in Pasadena, California with offices in Santiago, Chile. Our mission is to design, build, and operate the Giant Magellan Telescope to enable cutting-edge research and scientific observations that will revolutionize humanity’s fundamental understanding of the Universe. The 30-meter-class telescope is under construction at Las Campanas Observatory in Chile’s Atacama Desert, one of the best locations on Earth to explore the heavens. When complete in the early 2030s, the “extremely large telescope” will be the largest public-private funded science project in history.

The initial concept for the Giant Magellan Telescope grew from a series of discussions between Carnegie Science, Harvard University, Massachusetts Institute of Technology, Smithsonian Institution, University of Arizona, and the University of Michigan in the early 2000s. The goal was to advance the future of ground-based optical infrared astronomy well beyond the capabilities of existing 10-meter class telescopes. The result was a 30-meter class, extremely large, segmented optical infrared telescope design using giant primary mirrors based on the heritage of the twin Magellan Telescopes and the Large Binocular Telescope.
