CTAO-South Rendering (IMAGE) Cherenkov Telescope Array Caption This image illustrates the Alpha Configuration of the CTAO's southern hemisphere site or CTAO-South. The array is located less than 10 km southeast of the European Southern Observatory’s (ESO’s) existing Paranal Observatory in the Atacama Desert in Chile, which is considered one of the driest and most isolated regions on Earth – a paradise for stargazers. For the approved Alpha Configuration, the plan is for the site to host 14 Medium-Sized Telescopes to cover CTAO’s core energy range and 37 Small-Sized Telescopes to cover the CTAO’s highest energy gamma rays. The Alpha Configuration does not consider LSTs in the CTAO's southern array, but it includes the preparation of the foundation for four of them, as well as the foundation for three more SSTs, to allow for the construction of these telescopes in a future enhancement of the array.
