June – Moonset over ALMA

The last light of sunset sinks below the horizon of Chile’s Chajnantor plateau, silhouetting the Atacama Large Millimeter/submillimeter Array (ALMA). The giant array of individual antennas work as one to study the light from some of the coldest objects in the Universe, such as vast clouds in interstellar space or the first stars and galaxies that emerged from the “dark ages” of the Universe many billions of years ago. This image was taken during the ESO Ultra HD Expedition.
