Giant Magellan Telescope mirrors one and two
The first two mirrors for the Giant Magellan Telescope sit in the University of Arizona's Steward Observatory Mirror Lab. Mirror one, on the left, is complete, and has a protective coating. Mirror two, on the right, has been cast and is awaiting front surface polishing. Each mirror has a diameter of 8.4 meters, and the finished telescope will have seven mirrors, giving it an effective aperture of 24.5 meters (80 feet).
