With its 500-meter diameter, 10,000 tons of steel, and millimeter-level precision, this megastructure listens to radio signals from the far reaches of the cosmos. Built after 25 years of research and nearly 10 years of construction, FAST is pushing the boundaries of modern astronomy. Its giant deformable reflector, its cabin suspended 140 meters above the Earth, and its 19 ultra-sensitive antennas allow it to observe the invisible: pulsars, hydrogen clouds, dark energy… and perhaps even extraterrestrial signals. Capable of mapping the Milky Way, studying the expansion of the universe, and detecting cosmic phenomena never before observed, FAST represents a major technological leap. Thanks to its unique mechanics and robotic targeting system, it can track objects located billions of light-years away. More than just a telescope, FAST is an extraordinary machine designed to answer one of humanity's greatest questions:
