China claims to have received signals from extraterrestrial life

Scientists have not yet determined whether or not human activity is the source of radio interference.

 

According to a story recently published on the Chinese government's website but was subsequently taken down by its authors, China asserts that its giant "Sky Eye" telescope may have picked up trace signals from a distant alien civilization.

 

According to a report published on Tuesday (June 14) in Science and Technology Daily, the official newspaper of China's Ministry of Science and Technology, astronomers from Beijing Normal University have found "several cases of possible technological traces and extraterrestrial civilizations from outside the Earth." This discovery was made following the claims made in the report.

 

The signals were picked up by China's five-hundred-meter Aperture Spherical Radio Telescope (FAST), the largest radio telescope in the world and goes by the nickname "Sky Eye." In 2019, the Sky Eye instrument was used to investigate deep space for radio signals that might reveal the presence of extraterrestrial life. After combing through the collected data in 2020, the researchers discovered two suspicious narrow-band radio transmissions that might be artificial. The odd narrow-band radio signal was discovered again in 2022 during a targeted study of known exoplanets, bringing the total number of signals discovered to three.

 

Because the transmissions are narrow-band radio waves, which are generally utilized by only human aeroplanes and satellites, it is possible that they were generated by technology from another world. However, the scientists advise that their findings should be taken with a grain of salt until the investigation is finished because they are only preliminary.

 

According to Zhang Tongjie, head scientist of the China Extraterrestrial Civilization Research Group at Beijing Normal University, who spoke with the Science and Technology Daily, "These are several narrow-band electromagnetic signals that are different from the past, and the team is currently working on further investigation." "There is a great probability that the strange signal is some form of radio interference; nonetheless, this hypothesis needs to be verified or refuted before further investigation." This may take some time.

 

After being published, the report was promptly shared on the Chinese social media platform Weibo and taken up by several other state-run sites around the same time. It's not apparent why its abrupt removal occurred in the first place.

 

It is not the first time scientists have been perplexed by radio waves from intense space; the signals are only the most recent example. The Big Ear telescope picked up a mighty, minute-long electromagnetic burst at Ohio State University in August 1977 during a SETI (Search for Extraterrestrial Intelligence) search. The burst flared at a frequency scientists believed could be used by extraterrestrial civilizations. Jerry Ehman, the scientist, working with the telescope that night, scrawled "Wow!" in red pen on the sheet as soon as he noticed the signal on a data printout. This is how the finding came to be known by its now-famous name.

 

According to a previous post by Live Science, subsequent searches conducted in the same region of space came up empty. The subsequent study revealed that the signal may have originated from a sun-like star located in the constellation Sagittarius. However, the signal's origin is still a mystery at this point.

 

Radio interference is a known culprit in the past for derailing the efforts of scientists looking for extraterrestrial life, which is why Chinese astronomers are eager to rule it out. In 2019, astronomers discovered a signal sent to Earth from the star system Proxima Centauri, which is the star system closest to our sun (located approximately 4.2 light-years distant) and is home to at least one planet that may be habitable.

 

Because the signal was a radio wave with a narrow band, usually linked with things manufactured by humans, researchers were encouraged to consider the intriguing possibility that it originated from alien technology. According to a study that Live Science published, new research two years later showed that the signal most likely originated from a failing piece of human technology. Similarly, a well-known group of signals that were formerly thought to have originated from extraterrestrial beings and that were discovered between 2011 and 2014 were determined to have been produced by scientists microwaving their meals.

 

Tonjie has said that his team intends to take additional observations of the odd signals to unequivocally rule out the possibility of any radio interference and get as much information about them as possible.

 

In an interview with the Science and Technology Daily, Zhang said, "We look forward to the [FAST telescope] being the first to detect and confirm the presence of extraterrestrial civilizations."

 

The disparity between the size and age of the universe and the observation that there do not appear to be any intelligent life-forms beyond Earth is known as the Fermi Paradox. This disparity has long been a source of consternation for scientists. After pondering the riddle, the Nobel Prize-winning physicist Enrico Fermi is rumoured to have famously commented, "So where is everybody?" This is where the paradox gets its name, as it was during one of his casual lunchtime reflections that he came up with the idea.
