China says it has received signals from aliens - Incredibilia.ro

China claims that its giant “Sky Eye” telescope captured signals from an extraterrestrial civilization, according to a report recently posted and later deleted by Chinese scientists.

Astronomers at Beijing Normal University have discovered “several cases of possible traces of technology and civilization outside the Earth,” according to a report published on June 14 in the Science and Technology Daily, the official newspaper of the Chinese Ministry of Science and Technology.

The signals were picked up by China’s five-hundred-meter spherical aperture (FAST) radio telescope, dubbed the Sky Eye, which is the world’s largest radio telescope.

In 2019, Sky Eye was set to scan outer space for radio signals that could indicate extraterrestrial life. Examining these data in 2020, the researchers said they had spotted two potentially artificial “suspicious” narrowband radio signals.

Then, in 2022, a targeted study of known exoplanets found another “weird” narrowband radio signal, bringing the number to three.

Since the signals in question are narrowband radio waves, usually used only by aircraft and artificial satellites, they could have been produced by extraterrestrial technology. However, scientists say their findings should be taken with caution until the analysis is complete.

“These are different narrowband electromagnetic signals from the past, and the team is now working on further investigations,” Zhang Tongjie, chief researcher of the Alien Civilizations Research Group at Beijing University, told Science and Technology Daily.

“The possibility that the suspicious signal is a kind of radio interference is also very high, and must be further confirmed and ruled out. It could be a long process, “he said.

Following the publication, the report quickly circulated on the Chinese social network Weibo and was taken over by a number of other state publications. The reasons behind its sudden deletion are unclear.

This is not the first time that scientists have been confused by radio waves in outer space. In August 1977, SETI (Search for Extraterrestrial Intelligence) research conducted by Ohio State University’s Big Ear Telescope detected an incredibly powerful, one-minute electromagnetic explosion at a frequency that scientists suspected. that it could be used by extraterrestrial civilizations.

After noticing the anomaly, the scientist working with the telescope that night, Jerry Ehman, hurriedly scribbled “Wow!” with a red pen on the page, giving the signal its famous name.

Subsequent research in the same region of space has all returned “empty-handed,” and later studies have suggested that the signal may have come from a Sun-like star in the constellation Sagittarius, Live Science reported earlier. However, the source of that signal is still a mystery.

Chinese astronomers are keen to rule out radio interference, as it has also prevented “alien hunters” in recent years. In 2019, astronomers spotted a signal sent to Earth from Proxima Centauri – the closest star system to our Sun (about 4.2 light-years away) and which hosts at least one potentially habitable planet.

The signal was a narrowband radio wave, usually associated with man-made objects, which led scientists to think of the interesting possibility that it came from an alien technology.

However, new studies, published two years later, have suggested that the signal was most likely caused by a malfunction of human technology. Similarly, another famous set of signals that were once thought to have come from aliens, detected between 2011 and 2014, turned out to have been actually produced by researchers heating their microwave lunches.

Tonjie added that his team plans to make repeated observations of the strange signals in order to conclusively rule out any radio interference and to obtain as much information as possible about them.

“We look forward to the FAST telescope being the first to discover and confirm the existence of extraterrestrial civilizations,” Zhang told the Science and Technology Daily.

The discrepancy between the size and age of the universe and the apparent lack of intelligent life forms beyond Earth – called the Fermi Paradox – has long troubled scientists.

The paradox derives its name from the casual lunchtime reflections of Nobel laureate physicist Enrico Fermi, who, after contemplating the enigma, is said to have remarked: “Where is everyone (in the universe)?”
