The Giant Magellan Telescope (GMT) will be the world's largest telescope when it is completed in 2025. Instead of one large mirror, the GMT will have seven separate mirrors working together. This will mean its collecting area is bigger than the actual mirror surfaces. It will be made of seven 8.4 m (27.6 ft) diameter mirror parts. It will have a the resolving power of a 24.5 m (80.4 ft) mirror. Its collecting area will be the same as a 21.4 m (70.2 ft) mirror. The telescope will have over four times the ability to gather light than existing telescopes. It will produce images up to ten times clearer than the Hubble Space Telescope. It will cost $700 million.
