This is a stunning time-lapse video of an entire night at the ALMA Array Operations Site in Chile (the largest astronomical project in existence). The antennas point at the same part of the sky at any given moment, so their movements are perfectly synchronized. If you think watching a sunset is beautiful, wait till you see our galaxy come into view in this video.
P.S. This video could do with music. We recommend playing some Sigur Ros in the background while watching this.
