In their new book, Skyglow, the duo, who met studying film in Los Angeles, show off a breathtaking array of time-lapse images and astral photography that capture the beauty of the night sky (it?s easy to see why the Rolling Stones even used some of their images as visuals for a recent tour).

The exponential growth of light pollution shows how modern life is robbing us of views of the night sky.

In addition to a growing population and bigger and bigger cities, one of the prime culprits behind brighter evenings is a new type of lighting. The large-scale switch over to LED lights has been a...
