CTAO-North Rendering (IMAGE) Cherenkov Telescope Array Caption This is an artistic rendering of the CTAO's northern hemisphere site or CTAO-North. The site already hosts a prototype of the Large-Sized Telescope, the LST-1 (top left), but the plan is for the site to host four LSTs and nine Medium-Sized Telescopes (MSTs) to cover CTAO’s low and medium energy range. The array is located on the existing site of the Instituto de Astrofísica de Canarias’ (IAC’s) Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands (Spain). At 2,200 metres altitude and nestled on a plateau below the rim of an extinct volcanic crater, the site currently hosts a variety of telescopes operating at different wavelengths, including the Telescopio Nazionale Galileo (TNG) and Gran Telescopio de Canarias (GTC), visible in the upper part of the image, as well as CTAO predecessor the Major Atmospheric Gamma-Ray Imaging Cherenkov (MAGIC) telescopes (not pictured).
