context_page_description: The Calar Alto Observatory is an astronomical observatory located in Almería province in Spain on Calar Alto, a 2,168-meter-high mountain in the Sierra de Los Filabres range.
  Until 2018, Calar Alto was owned and operated jointly by the German Max Planck Institute for Astronomy in Heidelberg, and the Spanish Institute of Astrophysics of Andalusia in Granada. It was named Centro Astronómico Hispano-Alemán / Deutsch-Spanisches Astronomisches Zentrum, "German–Spanish Astronomical Centre". In 2019, the Council of Andalusia takes over the German partner, sharing the observatory with the Spanish National Research Council through its head institute, IAA-CSIC.
  Calar Alto telescopes are used for a broad range of observations, from objects in the Solar System to cosmology, including the search for exoplanets.
  The 3.5-meter telescope is the largest telescope in mainland Europe, though there are three larger telescopes on the Spanish island of La Palma at the Roque de los Muchachos Observatory. The minor planet 189202 Calar Alto, discovered by Felix Hormuth at Starkenburg Observatory in 2003, was named in honor of the observatory site.

  Calar Alto telescopes are used for a broad range of observations, from objects in the Solar System to cosmology (the Alhambra and CALIFA surveys), including the search for exoplanets (the CARMENES survey).
