🔭 Largest Radio Telescope in the World

The largest radio telescope in the world is the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), located in Guizhou Province, China. It was completed in 2016 and began its operation in 2019.

FAST has a diameter of 500 meters and consists of 4,450 panels that make up its spherical reflecting surface. It is designed to be highly sensitive and able to detect weak radio signals from distant objects in the universe, such as pulsars and galaxies. It is capable of detecting signals from up to 11 billion light-years away and has a potential survey area of about 2/3 of the sky.

The construction of FAST is part of China's efforts to become a major player in space exploration and scientific research. It is operated by the National Astronomical Observatories of China (NAOC) and is open to international researchers.
