Leveraging U.S. manufacturing, it promises unparalleled astronomical insights and aims for operation by the decade’s end. Credit: GMTO Corporation
Seven of the world’s largest mirrors will search the Universe for life beyond Earth
The Giant Magellan Telescope begins the four-year process to fabricate and polish its seventh and final primary mirror, the last required to complete the telescope’s 368 square meter (3,961 square foot) light collecting surface, the world’s largest and most challenging optics ever produced.
Together, the mirrors will collect more light than any other telescope in existence, allowing humanity to unlock the secrets of the Universe by providing detailed chemical analyses of celestial objects and their origin.
Last week, the University of Arizona Richard F. Caris Mirror Lab closed the lid on nearly 20 tons of the purest optical glass inside a one-of-a-kind oven housed beneath the stands of the Arizona Wildcats Football Stadium.

The spinning oven will heat the glass to 1,165°C (2,129°F) so as it melts, it is forced outward to form the mirror’s curved paraboloid surface. Measuring 8.4 meters (26.7 feet) in diameter—about two stories tall when standing on edge—the mirror will cool over the next three months before moving into the polishing stage. READ MORE...
