The results of decoding a mysterious radio signal that have puzzled scientists for nearly half a century suggest that it may come from a “twin” world with us, located in the constellation Sagittarius.
Research just published in the International Journal of Astrobiology from independent astronomer Alberto Caballero has identified the famous radio signal “Wow!” in the SETI Institute (Search for Extraterrestrial Intelligence) data actually comes from a solar system-like world.
Appeared in a SETI search through the Big Ear telescope of Ohio State University (USA), Wow! extremely powerful but very short, lasting only 1 minute 12 seconds, as reported by astronomer Jerry Ehman, who discovered it on August 15, 1977.

Data from the Big Ear telescope has now been decoded to look for messages in the electromagnetic frequency band 1420.4056 megahertz, produced by the element hydrogen.
“Since hydrogen is the most abundant element in the universe, it’s completely logical to predict that a Milky Way galactic civilization that wants to draw attention to itself could signal at or near the same frequency. number of the neutral hydrogen line” – Space newspaper quoted Dr. Ehman.
It is the same thing that guided Alberto Caballero’s research. This astronomer said that following these things, compared with the list of stars from the European Space Agency’s Gaia satellite, he identified the “hometown” of the Wow! radio signal.
That is 2MASS 19281982-2640123 about 1,800 light-years away from us with a temperature, diameter and luminosity close to our Sun, which means it is very likely to have an Earth-like planet.
According to the report, the possibility that this radio signal came from a natural phenomenon cannot be ruled out, but so far no natural phenomenon has really matched the characteristics of Wow!, hence the human hypothesis. Aliens are still something to look forward to.
Astronomers hope the answer will become clearer when future telescopes are capable of peering through the atmospheres of distant Earth-like planets.
