To the naked eye, the night sky seems to be a fixed, unchanging darkness. But astounding beauty is hidden just beyond the limits of our (unaided) human perception. As the Earth rotates, time-lapse photography captures what our eyes can’t perceive, and it is breathtaking. This video was photographed in 2011 in South Dakota, Utah and Colorado. Randy Halverson’s work attracted the attention of Bear McCreary, a composer who wrote the music for the TV show Battlestar Galactica, so he scored Halverson’s timelapse just for the hell of it. This is the result.
