China's celestial eye first detected the "mysterious radio signals in the deep universe". On the 4th, the FAST Project Department of the National Astronomical Observatory of the Chinese Academy of Sciences said that it was the first time that FAST detected repeated bursts of fast radio storms and captured the largest number of pulses known in the world. Scientists say that the "mysterious radio signal in the deep universe" is about 3 billion light-years away from the Earth, and interference factors such as aircraft and satellites have been excluded. Follow-up cross-validation is under way.
In 2015, the Arecibo Telescope first detected a repetitive burst of the fast radio storm FRB121102. According to data analysis, the signal source is located in a dwarf galaxy about 3 billion light-years away from Earth. Zhang Xinxinxin, an assistant engineer at the National Observatory of the Chinese Academy of Sciences, said that it was FRB121102 that was detected by FAST using real-time detection terminals.
