Patricio Guzman's 'Nostalgia for the Light' is a wonderful documentary 'about' Atacama. It cuts between the scientists using the telescopes and a collection of women who have been scouring the desert for fragments of the bodies of loved ones discarded during the pinochet regime. Both are using the space to probe history, just very different kinds and at very different scales. Very powerful and instructive exploration of the (dead) body, grief, and the necessity of 'witnessing'. Highly recommend it to everyone here!
