Chinese scientists claim to have discovered what they believe to be traces of an alien civilization's signal. As part of their search for evidence of aliens, researchers have found "strange" signals from outer space and are trying to figure out what they are. China's FAST radio telescope, commonly known as the "Sky Eye" telescope, picked up the signals. With a dish diameter of 1.600 feet, it is the world's largest telescope of its kind and has been investigating possible alien life since 2020.
The Chinese state-run Science and Technology Daily reported on Tuesday that researchers led by professor Zhang Tongjie, chief scientist of Beijing Normal University's China Extraterrestrial Civilization Research Group, have discovered a number of "possible technological traces" from intelligent civilizations elsewhere in the cosmos. Photographed by the FAST telescope in Pingtang County, China, in September 2016. The huge telescope is used to search for extraterrestrial broadcasts.
The FAST telescope searches the sky for certain radio waves that can be produced artificially. These narrowband transmissions also need to be distinguished from the background noise of other deep space radio emissions that require the use of sensitive equipment. Exoplanets, planets orbiting stars other than the Sun, were some of the telescope's targets.
According to Science and Technology Daily, Tongjie and his team discovered two sets of "strange" signals in 2020, and a third was discovered this year.
The signals are not yet evidence of extraterrestrial life. Tongjie told the news outlet: “The possibility that the suspicious signal is radio interference is also very strong and should be further verified and ruled out. This can be a long procedure.”
He went on to say that the team will use the telescope to repeat observations of "strange signals" to see if they can get more information. Unidentified radio transmissions from space are not uncommon and often lead to assumptions about a possible source of intelligence. However, such signals are often explained as having a natural source, especially an active star.
Discovered in 1977 by Ohio State University's Big Ear telescope, the signal is perhaps the most famous strange space signal ever observed. The very loud signal vibrated for just over a minute on a famous radio astronomy frequency that experts suspect is used by an alien civilization. Jerry Ehman, a scientist working on the telescope, circled the signal with a red pen and said, "Wow!" Wrote. next to when it is shown in a data output. The source of the signal is still unknown.
Still, experts believe that an alien civilization as advanced as ours or more advanced than us, 1974 Arecibo He believes he can send artificial radio signals into space for us to explore, like an interstellar radio signal containing information about humanity and Earth.
The SETI Institute is an organization that has spent years using enormous arrays of radio telescopes to search for such radio signals. To date, no radio broadcasts that can be considered as originating from a foreign civilization have been encountered.
The apparent scarcity of aliens has led to the Fermi paradox, which describes the contradiction between mathematical predictions that alien life should exist in our galaxy and our lack of vision.
For example, some scientists believe that our galaxy contains tens of thousands of alien civilizations.
Some possible solutions to the Fermi paradox include exaggerating life's shared intelligence, the intelligent life deciding not to send information, or not seeing or understanding such information.
