Big Astronomy: People, Places, Discoveries explores three observatories located in extreme environments and remote locations in Chile. Due to its special climate and location, which creates stable, dry air Chile is one of the best places in the world for astronomy. By 2022, 70% of the world's optical and infrared collecting power will be located in Chile. With a focus on STEM (science, technology, engineering and math) the film highlights the multitude of careers needed to keep the great observatories working.
