Giant Magellan Telescope Completes Final Mirror for Unprecedented Observations

The Giant Magellan Telescope project has cast its seventh and final mirror, marking a significant milestone in the construction of the telescope. The mirror, made of high-quality optical glass, will take four months to cool before technicians begin grinding and polishing its surface to an astronomically precise finish. Once completed, the mirror will join its six counterparts in Chile, where the telescope is being built. The Giant Magellan Telescope is expected to provide unprecedented capabilities for studying planets and making new discoveries in the field of astronomy.
