livescience has Report Quoting research, I have written that this is possible. Alberto Caballero, the sole author of the study, is an iPhD student at the University of Vigo in Spain. Caballero is no astrophysicist, but he wrote Wow! (Wow!) has published a study on the signal. It is also said about the wave signal that through this the aliens tried to contact the earth. This thing is from the year 1977. A narrowband radio signal was detected by a radio telescope in the US. This is known as the Wow signal.
Regarding the source of this signal that came half a century ago, scientists have speculated that it must have come from a Sun-like star located 1800 light-years away in the constellation Sagittarius. Many scientists believe that there is such an intelligent civilization in our galaxy, which wants to tell about itself. Probably he was the one who broadcast the signal.
In his research, Caballero calculated attacks on Earth, including the WO signal. This was then applied to the estimated number of exoplanets in the Milky Way. Caballero has come to know in his calculation that four civilizations can possibly attack the earth. He has warned scientists to be careful while practicing Messaging Extraterrestrial Intelligence (METI). Significantly, through this technique, efforts are made to contact other planets. Caballero fears that using METI in the wrong and excessive ways could provoke aliens to attack.
