🧠 Explanation:
China launched the “Sky Eye” telescope, officially the Five-hundred-meter Aperture Spherical Telescope (FAST), in 2016 to search for extraterrestrial life and study the universe. Located in Guizhou, it’s the world’s largest single-dish radio telescope, capable of detecting faint signals from distant galaxies. FAST explores pulsars, dark matter, and potential alien signals, advancing astrophysics. Its massive size and sensitivity make it a groundbreaking tool in space research, reflecting China’s growing scientific ambitions. Sky Eye’s contributions enhance our understanding of cosmic phenomena, positioning China as a leader in global astronomical exploration.
