High up on Chile's cold, dry Chajnantor Plateau, 66 giants stand under the starry night sky. They gaze upwards, moving with the celestial objects on which they have set their sights. These are the powerful antennas of the Atacama Large Millimeter/submillimeter Array.
The setup has been operational since March 2013, and together the antennas make up the newest, largest, strongest and most expensive radio telescope currently operating on Earth. The images they produce have 10 times the clarity of those yielded by the Hubble Space Telescope.
