This is being reported by Bloomberg, among other sources:
China said its giant Sky Eye telescope may have picked up signs of life beyond Earth, according to a report by the state-backed Science and Technology Daily, which then appeared to have deleted the report and posts about the discovery.
The narrow-band electromagnetic signals detected by Sky Eye – the world’s largest radio telescope – differ from previous ones captured and the team is further investigating them, the report said, citing Zhang Tonjie, chief scientist of an extraterrestrial civilization search team co-founded by Beijing Normal University, the National Astronomical Observatory of the Chinese Academy of Sciences and the University of California, Berkeley.
The suspicious signals could, however, also be some kind of radio interference and requires further investigation, Zhang added.
It isn’t clear why the report was apparently removed from the website of the Science and Technology Daily, the official newspaper of China’s science and technology ministry, though the news had already started trending on social network Weibo and was picked up by other media outlets, including state-run ones.
Here is a flashback article from 2016 where it was described what China’s plans were with this telescope.. they made it known they were going to search for alien life..
