The GMT is an international effort to create a telescope that delivers images 10 times clearer than those produced by the Hubble Space Telescope. When it's up and running, the GMT will help scientists tackle some of the biggest questions, like are we alone in the universe? It will allow astronomers to collect more light than any telescope ever built and at the highest resolutions yet.
But achieving this is no simple task. The team broke ground in 201
While this second segment took seven years, the University of Arizona was able to significantly speed up the front surface polishing process. The GMT team hopes replicating the technique will help future segments get through production even faster.
