ESO ALMA Antenna

Time-lapse of a whole night at the ALMA Array Operations Site (AOS):

[needs a cool soundtrack!]

"As the sky appears to rotate clockwise around the south celestial pole (roughly on the upper left edge of the video), the Milky Way goes down slowly, until it is lying almost horizontal before sunrise. The center of our galaxy becomes visible during the second half of the night as a yellowish bulge crossed by dark lanes in the center of the image, just above the antennas."
