Calar Alto Observatory

Ground-Based Optical Observatories

A German-Spanish astronomical observatory, the Centro Astronómico Hispano en Andalucía, on the 2,168-meter Calar Alto mountain in the Sierra de Los Filabres, Almería province, Spain. Proposed in 1970 and officially opened in July 1975 with its first telescope, it now hosts four main telescopes and is used for research ranging from Solar System objects to cosmology, including the ALHAMBRA and CALIFA surveys and the CARMENES exoplanet search.
