The apparent signals were captured by the FAST radio telescope in China.

Yesterday, Science and Technology Daily, a state-backed media outlet in China, published what could have been an exciting piece of news. Did aliens make their way to Earth? Science and Technology Daily quickly pulled the story from its website because it wasn't related to aliens.

According to the article from Science and Technology Daily, the observations came from the Sky Eye Telescope in China. The biggest radio telescope in the world is 500 meters (1,640 feet) high.

The article is written in a language other than English.

A few days ago, Professor Zhang Tongjie, chief scientist of the China Extraterrestrial Civilization Research Group of the Department of Astronomy and Extraterrestrial Civilization Research Group of Beijing Normal University, revealed that his team used the “Chinese Sky Eye” to discover several cases of possible technological traces and extraterrestrial civilizations from outside the earth... Zhang Tongjie said that these are several narrow-band electromagnetic signals different from the past, and the team is currently working on further investigation.

...in 2020, the team discovered two groups of suspicious signals of extraterrestrial civilizations during the data processing of the “China Sky Eye” 2019 synchronic sky survey observations. In 2022, the team found another suspicious signal from 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...

For now, we have no information about the signals, but it is most likely that they came from a natural phenomenon. The search for extraterrestrial intelligence is an important one, which is why the scientists should share what data they have with the larger research community.

Astronomers have picked up radio signals before, but couldn't explain them. The scientists in the Breakthrough Listen project recorded a burst from Proxima Centauri. The signal was picked up by a telescope at the parkes observatory. The signal was probably emitted from Earth in a way that fooled the telescope. The Canadian researchers caught a burst of radio waves from a star. The signal was traced back to the microwave.

SETI is a rigorous scientific endeavor that relies on transparent data collection, peer review, and heaping amounts of skepticism. It is not clear why this recent report from China was shared and then deleted, but we will learn more about these apparent signals.
