Giant Magellan Telescope Project Finishes 2nd Primary Mirror

August 12, 2019

The GMT is taking shape on a mountaintop in the Chilean Andes. The telescope will feature seven primary mirrors, which together will create a light-collecting surface 80 feet (24.5 m) wide. The powerful scope will allow astronomers to investigate some of the cosmos' deepest mysteries -- the nature of dark matter and dark energy, for example, and whether Earth life is alone in the universe.
