The largest visible light telescope is the Gran Telescopio Canarias (GTC) located in the Canary Islands, Spain. It has a primary mirror with a diameter of 10.4 meters, making it one of the largest optical telescopes in the world.
Currently the largest optical telescope is "The Great Canary Telescope" (Gran Telescopio Canarias) in Spain, it has an apeture of 10.4 metres. There is an optical telescope under construction in Chilie that when completed will have an apeture of 21.4 metres, called the Giant Magellan Telescope. The largest single dish apeture radio telescope is the Arecibo Radio Telescope in Puerto Rico which is 305 metres.
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
The largest optical telescope in the world today is the Gran Telescopio Canarias (Grand Canary Telescope) in Spain, with an effective diameter of 10.4 meters. The world's largest individual radio telescope is the RATAN-600 in Russia, with the effective diameter of a 600 meter dish.
"Optical", in this case, simply means that they work with light.
The Keck Observatory in Hawaii is a 10 meter optical telescope. Even larger is the Great Canary Telescope off the coast of Africa (west of Morocco) at 10.4 meters. EU scientists have requested permission to build a 40 meter optical telescope. The largest single radiotelescope dish is Arecibo.
No, the biggest telescope in the world currently is the Large Binocular Telescope. But Hubble is the biggest spacetelescope.
