My Mrs is an astrophysicist and has been to Chile about 10 or so times over the last 8 years. She says the Atacama desert is ideal because of Chiles political stability as well as stability of the atmosphere. A high and dry western coastline is good for great “seeing” conditions because highly stable sea air is less prone to fluctuations in temperature which is the bane of any astronomer (this is what creates twinkling of stars). As it happens she was working on the data reduction pipeline for an instrument with adaptive optics (AO) on the Gemini South telescope. AO helps reduce atmospheric disturbances even further so they are now getting better results than Hubble from a ground based telescope.
