Gran Telescopio Canarias, Optical telescope at Roque de los Muchachos Observatory, La Palma, Spain
The Gran Telescopio Canarias is a large optical observation facility at Roque de los Muchachos Observatory on La Palma. Its primary mirror consists of 36 hexagonal segments controlled by advanced optical systems.
The project began in 1987 as a major international effort involving more than 1000 workers from around 100 companies. First observations took place in 2007, marking the start of its research operations.
The facility brings together researchers from multiple countries working on shared projects, fostering international scientific collaboration. This global cooperation has established it as a significant center for astronomical research.
The facility sits at 2267 meters elevation where minimal light pollution and clear skies provide optimal observation conditions. The high altitude location makes it a preferred site for astronomers seeking stable weather patterns.
The facility is equipped with a MEGARA spectrograph that analyzes visible light and near-infrared radiation. This capability enables detailed studies of celestial objects across wavelength ranges that are particularly valuable for modern astronomy.
