The Giant Magellan Telescope (GMT) is slated to be the first in a new class of extremely large telescopes, capable of producing images with 10 times the clarity of those captured by the Hubble Space Telescope. The GMT will reveal the faintest objects ever seen in space, including extremely distant and ancient galaxies. The telescope will be built in the dry, clear air of Chile's Atacama Desert in a dome 22 stories high. GMT is expected to see first light in 2021 and be fully operational by 2024.
