China says the world's largest FAST or Sky Eye radio telescope has picked up a signal from an alien civilization. According to Bloomberg, the announcement was published by state-owned Science and Technology Daily, which then deleted the post about the discovery..

The narrow-band electromagnetic signals that FAST recorded are different from those that were recorded before, researchers continue to study them. The discovery was announced by Zhang Tongjie, chief scientist of the extraterrestrial civilization search group, which was established by Beijing Normal University, the National Astronomical Observatory of the Chinese Academy of Sciences and the University of California at Berkeley..

However, it is not clear why the report was removed from Science and Technology Daily, the official newspaper of China's Ministry of Science and Technology.. The news has already begun to spread on the Weibo social network, and was also picked up by other media, including state-owned ones..

Sky Eye telescope with a diameter of 500 meters officially began the search for extraterrestrial life in September 2020. Zhang said the team detected two sets of suspicious signals in 2020 from data collected in 2019 and another in 2022 from exoplanet observations..

The telescope is extremely sensitive to the low-frequency range and plays one of the main roles in the search for alien civilizations.. However, Zhang noted that the unusual signal may be radio interference and needs further investigation..

Previously, scientists used a new methodology to count the number of alien civilizations that could exist in the Milky Way.. It turned out that there can be at least 36 civilizations advanced enough to broadcast signals into space..
