ALMA under the Milky Way (time-lapse)

Time-lapse video of the ALMA antennas taking observations of the night sky over their location in the Atacama Desert. The Milky Way can be seen as a bright band overhead. These particular antennas were contributed by the National Astronomical Observatory of Japan (NAOJ), one of the international partners collaborating with ESO to run ALMA, which is the most powerful astronomical observatory of its kind.
