World’s largest telescope begins with a spin
Tucson, Arizona - Expert mirror makers are gearing up to cast the first component of what is planned be the world's largest telescope. When completed, its seven 8.4-metre mirrors will more than quadruple the power of today's best observatories.
Like other multiple-dish instruments, such as the four 8-metre dishes of the Very Large Telescope in Chile, the planned Giant Magellan Telescope will take advantage of its expansive surface area to boost its sensitivity to light.
