The world’s largest telescope was recently dedicated by Spanish King Juan Carlos.  The telescope, dubbed the Gran Telescopio Canarias (GTC) is located on Spain’s Canary Islands and is larger than Hawaii’s Keck Telescopes by .4 meters.  The GTC is 10.4 meters while Keck is 10 meters.

But, the GTC won’t hold the title of largest telescope for long with several larger scopes in the works.  The Giant Magellan Telescope, a 24 meter telescope, is planned for Las Campanas, Chile.  A 30 meter telescope is planned for Mauna Kea in Hawaii and has a completion date of 2018.  Finally, the European Extremely Large Telescope or E-ELT, is a 42 meter telescope.  A site for the E-ELT has not been selected yet, but sites in Argentina, Chile, Morocco and Spain are up for consideration.
