Tonjie has added that his team is planning to take repeat observations of the strange signals to conclusively rule out any radio interference and obtain as much information about them as possible. Similarly, another famous set of signals once supposed to have come from aliens, detected between 20, turned out to have actually been made by scientists microwaving their lunches. New studies released two years later, however, suggested that the signal was most likely produced by malfunctioning human technology, Live Science previously reported. The signal was a narrow-band radio wave typically associated with human-made objects, which led scientists to entertain the exciting possibility that it came from alien technology.

Nonetheless, the signal's source is still a mystery.Ĭhinese astronomers are keen to rule out radio interference because it has famously waylaid alien-hunting scientists in the recent past. Upon spotting the signal on a data printout, the scientist working with the telescope that night, Jerry Ehman, hastily scribbled 'Wow!' in red pen on the page, giving the detection its famous name.įollow-up searches in the same region of space have all returned empty-handed, and later research has suggested that the signal could have come from a sun-like star located in the constellation Sagittarius, Live Science previously reported. In August 1977, a SETI (Search for Extraterrestrial Intelligence) search performed by the Ohio State University's Big Ear telescope picked up an incredibly strong, minute-long, electromagnetic burst that flared at a frequency scientists suspected could be used by alien civilizations.

The signals aren't the first time that scientists have been baffled by radio waves from deep space. The reasons behind its sudden deletion are unclear. This may be a long process.'įollowing its publication, the report quickly began to circulate on the Chinese social media network Weibo and was picked up by a number of other state-run outlets. '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. 'These are several narrow-band electromagnetic signals different from the past, and the team is currently working on further investigation,' Zhang Tongjie, head scientist at the China Extraterrestrial Civilization Research Group at Beijing Normal University, told the Science and Technology Daily.
