ALMA repair close-up

The Atacama Large Millimeter Array (ALMA) is situated more than 5000 metres above sea level in the Chilean desert, on the Chajnantor plateau. Here, the dry air and thin atmosphere allow a spectacular view into the Universe and make it the perfect place for such a sensitive telescope. One of the telescope's 66 antennas is being worked on here by specialist engineers, in this close-up view.
