Time-lapse video of "the cleanest, darkest skies on Earth"

"I shot this film over 12 days around the San Pedro de Atacama region of Northern Chile," writes videographer Nicholas Buer. "San Pedro is an oasis town in the Atacama and sits at an altitude of 2600m. The town is a great base to explore the fascinating landscapes that surround it, and everything just goes up and up. The Atacama is well-known for what are arguably the cleanest, darkest skies on Earth."
