The Gran Telescopio Canarias (GranTeCan or GTC), also known as the Great Canary Telescope is a reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canaries, Spain. Construction of the telescope, sited on a volcanic peak above sea level, took seven years and cost €130 million (£112 million).〔 〕 Its installation had been hampered by weather conditions and the logistical difficulties of transporting equipment to such a remote location.〔 First light was achieved in 2007 and scientific observations began in 2009. The GTC Project is a partnership formed by several institutions from Spain and Mexico, the University of Florida, the Universidad Nacional Autónoma de México,〔(''GTC faq'' ) GTC digital 8 January 2009〕 and the Instituto de Astrofísica de Canarias (IAC). Planning for the construction of the telescope, which started in 1987, involved more than 1,000 people from 100 companies.〔 , it is the world's largest single-aperture optical telescope.〔 〕 The distribution of the availability of time to use the telescope meets its financial structure: 90% Spain, 5% Mexico and 5% the University of Florida. ==History== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gran Telescopio Canarias」の詳細全文を読む スポンサード リンク
