ALMA from the sky

High on the Chajnantor plateau in the Chilean Andes, the European Southern Observatory (ESO), together with its international partners, is operating the Atacama Large Millimeter/submillimeter Array (ALMA) — a state-of-the-art telescope to study light from some of the coldest objects in the Universe. This view from the sky gives us a broader view on the extension of this 66-antenna observatory that can be arranged in different configurations, where the maximum distance between antennas can vary from 150 metres to 16 kilometres.
