The world’s largest astronomical observatory is located in the southwest of China. Out of 400 other locations, a mountain valley was chosen, located almost a kilometer above sea level – it is ideally suited for its size and level of protection against radio frequency waves. The remote area, however, complicated the task for the builders, who had to live in a mountain gorge far from civilization, where at first there was no electricity. Construction began in 2011 and took five years. As a result, the largest spherical radio telescope on the planet was built, which is a 500-meter dish of 4400 aluminum panels. The observatory cost the state $ 180 million. The Chinese radio telescope stores an incredibly large amount of data and is able to detect even the faintest radio waves emanating from celestial objects, including pulsars and entire galaxies.
