On the morning of 20th, the year-end summary meeting of 2021 fast operation and development center was held at China sky eye (fast) observation base in Pingtang County, Guizhou Province. It is understood that at present, scientific achievements produced by fast telescope observation are constantly emerging. Fast has found 509 pulsars, more than four times the total number of pulsars found by all other telescopes in the world.

At present, more than 120 scientific research papers have been published based on fast data, with more than 590 citations. In the next stage, fast operation and development center will accelerate the construction of the State Key Laboratory of radio astronomy and technology.
