Scientists in the United States have begun fabricating and polishing the seventh and final primary mirror of the Giant Magellan Telescope. This will eventually complete its 368 square metre light collecting surface – forming the largest, most technically challenging optical system in astronomical history. When combined, all seven mirrors will collect more light than any other telescope in existence, making it a truly next-generation observatory.
