CTAO-South Rendering (IMAGE) Cherenkov Telescope Array Caption This image illustrates 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.
