A few days ago, Professor Zhang Tongjie, chief scientist of the China Extraterrestrial Civilization Research Group of the Cosmology and Extraterrestrial Civilization Research Group of the Department of Astronomy of Beijing Normal University, revealed that his team used the “Chinese Sky Eye” to discover theSeveral examples of possible technological traces and extraterrestrial civilization candidate signals from beyond Earth.Zhang Tongjie said, these are severalDifferent from the previous narrowband electromagnetic signals, the team is currently working on further investigation.
As the largest and most sensitive radio telescope in the world at present, the “China Sky Eye” is also highly expected in the search for extraterrestrial civilizations. This is also one of the five major scientific goals of “China Sky Eye”.
In 2018, “China Sky Eye” installed and debugged back-end equipment dedicated to the search for extraterrestrial civilizations. Its main function is to screen out useful narrow-band candidate signals from the vast sea of electromagnetic signals of “China Sky Eye”, while celestial objects and Artificial signals are excluded.
In September 2020, “China Sky Eye” officially launched the search for extraterrestrial civilizations. The search methods are mainly synchronous sky survey observations and exoplanet target observations.
Zhang Tongjie revealed,In 2020, the team found two sets of suspicious signals of extraterrestrial civilizations during data processing of the “China Sky Eye” 2019 synchronic sky survey observations. In 2022, the team found another suspicious signal from the exoplanet target observation data.
“The possibility that the suspicious signal is some kind of radio interference is also very high, and it needs to be further confirmed and ruled out. This may be a long process.” Zhang Tongjie said, the good news is that in the observation and data processing in recent years, For the FAST19 beam observation mode, the team proposed for the first time in the world the multi-beam matching mode for extraterrestrial civilization search and the frequency drift and polarization criteria of extraterrestrial civilization signals, which made the identification process of extraterrestrial civilization signals more scientific and complete.
