The Giant Magellan Telescope (GMT) - the product of more than a century of
astronomical research and telescope-building by some of the world's leading
research institutions - will open a new window on the universe for the 21st
century. Scheduled for completion around 2016, the GMT will have the resolving
power of a 24.5-meter (80 foot) primary mirror - far larger than any other
telescope ever built.
