At a height of almost ten thousand feet, astronomers from the entire world gather in the Atacama Desert to watch the stars, in Chile. The sky’s transparency allows them to see all the way to the edge of the universe. Below, the ground’s dryness preserves human remains intact, forever: mummies, explorers, miners, indigenous people, and the bones of the dictatorship’s political prisoners.

While scientists seek for extraterrestrial life, a group of women look among the rocks: they are in search of their relatives.
