“A History of the Sky”: The Passing of a Year in a Mosaic of Time-Lapses

Ken Murphy has completed his ambitious “A History of the Sky” project, which we first got a glimpse of in March of last year. Wanting to reveal the patterns of light and weather over the course of a year, Murphy installed a still camera on the roof of the Exploratorium in San Francisco, pointed at the sky and snapping a photo every 10 seconds around the clock.

After a year had passed, Murphy made this time-lapse mosaic, with each box — arranged chronologically — showing the time-lapse of a single day. They’re all synchronized by time-of-day, and provide an interesting way of looking how sunrises, sunsets, and weather change over the course of a year.
