Largest single-dish telescope opens to international researchers

Credit: National Astronomical Observatory of China/Chinese Academy of Sciences This is the Five-hundred-metre Aperture Spherical Telescope, or Fast for short. It is nestled in a natural basin surrounded by forest in Guizhou province in China, and is the world’s largest single-dish radio observatory. In 2021, it will be open to astronomers around the world. The dish, nicknamed the Sky Eye, has superior sensitivity to detect cosmic phenomena, and will be used in the search for signals from stars and galaxies and, perhaps, extraterrestrial life.
