Roque de los Muchachos Observatory ("Spanish: Observatorio del Roque de los Muchachos, ORM) is an "astronomical observatory located in the municipality of "Garafía on the island of "La Palma in the "Canary Islands. The observatory site is operated by the "Instituto de Astrofísica de Canarias, based on nearby "Tenerife. ORM is part of the "European Northern Observatory.
The "seeing statistics at ORM make it the second-best location for optical and infrared astronomy in the "Northern Hemisphere, after "Mauna Kea Observatory, "Hawaii. The site also has some of the most extensive astronomical facilities in the Northern Hemisphere; its fleet of telescopes includes the 10.4 m "Gran Telescopio Canarias, the "world's largest single-aperture optical telescope as of July 2009, the "William Herschel Telescope (second largest in Europe), and the "adaptive optics corrected "Swedish 1-m Solar Telescope, which provides the highest resolution solar imaging of any telescope.
The observatory began operation around 1984 with the "Isaac Newton Telescope, which was moved to La Palma from the "Royal Greenwich Observatory site at "Herstmonceux Castle in "Sussex, "England. The move was troubled, and it is widely recognized that it would have been cheaper to build a new telescope on-site rather than to move an existing one.
The observatory was first staffed by representatives from "Spain, "Sweden, "Denmark and the "United Kingdom. Other countries which became involved later include "Germany, "Italy, "Norway, the "Netherlands, "Finland, "Iceland, and the "United States.
The observatory was officially inaugurated on June 29, 1985, by the Spanish royal family and six European heads of state. Four helicopter pads were built at the observatory to allow the dignitaries to arrive in comfort. The observatory has expanded considerably over time, with the 4.2m "William Herschel Telescope opened in 1987, the "Nordic Optical Telescope in 1988 and several smaller solar or specialized telescopes; the "Telescopio Nazionale Galileo opened in 1998 and the "Gran Telescopio Canarias opened in 2006, with its full aperture in 2009.["citation needed]
A fire on the mountainside in 1997 damaged one of the gamma-ray telescopes, but subsequent fires in September 2005 and August 2009 did no serious damage to buildings or telescopes.
