Up to 2016, the biggest telescopes were composed of an array of antennas located in a particular site, like the one at Atacama Desert, in Chile. called ALMA (Atacama Large Millimeter/ Submillimeter Array). Its construction dates from 2004 and consists of sixty-six 8-to-12-meter diameter antennas aiming to receive millimeter wavelengths. Among others things, ALMA is capable of performing deep space detections, what allows to obtain information about the first stars and galaxies that emerged billions of years ago at huge distances from us. Due to the universe expansion, most of these objects’ emissions have stretched out to the millimeter and submillimeter wavelengths.
