New Era · New Landmark ｜ "Chinese Eyes": Ask the mystery of the ancient universe

Where does the universe come from and where will it go? Known as the "China Eye" 500 -meter -caliber -diameter spherical radio telescope FAST, can you see the edge of the universe?

After the older generation of astronomers represented by Nantiandong proposed in the 1990s, "China Sky Eye" has undergone demonstrations, projects, and hard construction. It will be opened on September 25, 2016 to enter the debugging period. On January 11, 2020, the "China Eye" was officially opened through the national acceptance and is currently the largest and most sensitive single -caliber radio telescope in the world.

Research on fast radio storms helps humans to better understand the origin of the universe. Fast radio power storm is called the "flash" in the universe by scientists. Its origin and physical mechanism are currently completely unknown, and it has also become the most popular research direction in the field of physical physics today.

Fast engineer Song Benning said: "The receiving area of ​​'China Sky Eye' is very large, so its sensitivity is very high. It can see the relatively weak pulse radiation that other telescopes can be seen. The advantages."

"FAST capture the world's largest fast radio storm sample" was selected for the top ten progress of Chinese science in 2021 announced in February this year.

At the same time, it is found that pulse star is one of the main scientific goals of international large -scale radio telescope observations. The pulse star is like the "lighthouse" in the universe. Its extremely stable rotation cycle can become a ultra -high -precision clock that humans measure the time and space of the universe.

As of now, Fast has discovered about 500 pulse stars, becoming the most efficient equipment in the world since its operation. The achievement of these results is closely related to the creative design of the technical team: Fast cable fixed 4,450 reflex units on the Internet can accurately locate and collaborate, covering nearly 60%of the sky.

Since the formal opening of the country's acceptance, FAST operating efficiency and quality have been continuously improved. The annual observation time is more than 5,300 hours, which has far exceeded the expected work efficiency of international counterparts.

Behind this is a group of young people who are only 35 years old who are only 35 years old who are silently paying and adhered to. They stayed in the electromagnetic silent district in the mountains all year round, dedicated youth, and did not regret it, making their own contributions to the operation and maintenance of the major power.

"I hope not to live up to Teacher Nan Rendong's expectations." Fast engineer Sun Chun said, "Because he said at the time, I hope that the latecomers use this telescope. The subsequent major results of the output provide a better foundation. "

On March 31, 2021, Fast officially opened to the world to collect an observation application to global astronomers, and launched a scientific observation in August 2021. FAST's pair of "wisdom eyes" will pierce the "outside of light years", leading humans to continue to explore to unknown zones.
