The Giant Magellan Telescope (GMT) is an astronomical observatory currently under construction in Chile's Atacama Desert. Once completed, it will feature seven large mirrors, each measuring 8.4 meters in diameter, which will work together to create a telescope with an effective aperture of 24.5 meters. This design will allow the GMT to capture incredibly detailed images of distant celestial objects. The GMT aims to advance our understanding of the universe by studying phenomena such as the formation of galaxies, the nature of dark matter, and the potential for life on exoplanets. It is part of a new generation of telescopes, including the James Webb Space Telescope and the European Extremely Large Telescope, that will revolutionize our view of the cosmos.
