The Arsibo Observatory was the world’s largest radio telescope for 53 years before the completion of the five-hundred-meter-aperture (FAST) spherical telescope in China in 2016; But the Chinese Observatory, located in Pingtang County, Guizhou Province, has overtaken Arsibo. The Arsibo radio telescope was completely destroyed after two cables failed this year, ending more than half a century of brilliant activity. Now, Fast is opening its doors to astronomers around the world.
Wang Gaiming“Our scientific committee intends to open Fest increasingly to the international community,” the inspector general of the Fast Operations and Development Center told AFP during a visit to the telescope. According to AFP, China will accept the requests of scientists in the coming year (2021) who are looking for the use of fast in their research from around the world.
The China Spherical Telescope, with its huge plate 500 meters in diameter, is not only larger than the newly demolished Arsibo Telescope; It is also three times more sensitive. In addition, Fast, which began operations in January this year, is surrounded by a five-kilometer radio-off area where cell phones and computers are not allowed. According to Gaiming, the makers of Fast took a lot of inspiration from the Arsibo structure in building this telescope.
Radio telescopes, such as the Fast, use antennas and radio receivers to detect radio waves from radio sources in the universe, such as stars, galaxies, and black holes. Scientists can also use these tools to send radio signals and even reflect radio waves from objects in the solar system, such as planets, to see what kind of information might be returned from them.
Researchers can not only explore the world using Fast; They also study alien worlds and determine whether they are in the near-life belts of their host stars, and ultimately seek extraterrestrial life. In 1974, scientists searching for extraterrestrial intelligence (SETI) in Arecibo sent an interstellar radio message to the Messier 13 star cluster in hopes of receiving confirmation of extraterrestrial intelligent life. This message is in collaboration Carl Siegen, A promoter of the famous science and astronomer, was written and contributed to the reputation of Arsibo and radio astronomy in general.
