ALMA and the Milky Way

Time-lapse video of ALMA, located 5000 metres above ground on the Chajnantor plateau in northern Chile. The sky and the Milky Way appears to rotate clockwise around the south celestial pole, due to the Earth's rotation. The antennas are lit up in green when they are not moving, as a safety precaution. ALMA, the Atacama Large Millimeter/submillimeter Array, is able to observe the Universe in radio wavelengths. This allows us to see cold dust and gas, whether it is as the centre of the Milky Way or out to the furthest stretches of the Universe.
