“The only potential Sun-like star in all the WOW! Signal region appears to be 2MASS 19281982-2640123,” says Caballero. By hunting for Sun-like stars amid the thousands that have already been spotted and identified by Gaia in this same corner of the sky, one strong candidate sticks out amid the multitudes. Now, using detailed 3D star maps created by data obtained from the European Space Agency's Gaia space observatory, Caballero has pieced together what he believes is a likely origin point of the famous WOW! message from deep outer space. However, most astronomers disagreed with the findings, including Ehman himself. Petersburg College astronomer Antonio Paris claimed to have discovered the origin point of the WOW! Signal, theorizing that it was caused by a then-uncatalogued comet now named 266P/Christensen. Eastern Daylight Savings Time on August 15, 1977. Recall that earlier scientists called the time of the first contact with aliens.Big Ear Radio Observatory and North American Astrophysical ObservatoryĪccording to Astronomy Magazine, amateur astronomer Alberto Caballero has just diligently tracked the signal's origin back to a candidate star that closely resembles our own Sun in a momentous find that could finally crack the heavenly mystery wide open.

The Wow source radio emission entered the receiver of the Big Ear radio telescope at about 11:16 p.m. Aliens can’t hear us, says astronomer so, we can. “Since hydrogen is the most common element in the Universe, there is logic in the assumption that an intelligent civilization in our Milky Way galaxy, wishing to attract attention to itself, could transmit a strong narrowband signal at the frequency of the neutral hydrogen line or close to it,” Ehman explained.Ĭaballero’s findings were published in the International Journal of Astrobiology. A: Our best SETI experiments to date could detect Earth-like leakage signals at no more than 1 light-year’s distance. The famous signal on the printout on August 15, 1977 Now disassembled Big Ear telescope was looking for messages in the electromagnetic frequency range of 1420.4056 megahertz, which is generated by a hydrogen element. The signal was incredibly strong, but very short and lasted only 1 minute and 12 seconds, according to a report written by its discoverer, astronomer Jerry Eyman.Īfter seeing the printout of the abnormal signal, Ehman highlighted it and even wrote the exclamation “Wow!” on the page, which became the name of this event. The signal was picked up by the Big Ear telescope of Ohio State University, which recently joined the SETI program. All because, according to scientists, life, as we know it, can most likely be formed in planetary systems with sun-like stars. However, a tiny hope for the artificial origin of the extraterrestrial message remains. It has been repeatedly proposed to expand the scope for SETI, and one of the suggested alternatives to radio is the biological media. The famous signal could come from the constellation Sagittarius from the star 2MASS 19281982-2640123 Its temperature, diameter and luminosity are almost identical to our Sun,” Caballero said. I found one particular sun-like star – this is an object designated as 2MASS 19281982-2640123, located about 1800 light-years away from us. “The Wow! signal most likely came from some natural phenomenon, not from aliens. However, do not think about the artificial origin of a distant radio message. Researchers now believe they have discovered where the famous alien 'Wow' signal originated from Last year, scientists at Harvard University suggested that FRBs could result from energy leaks from powerful transmitters built by alien civilisations in order to send giant light sail ships on interstellar voyages. The Wow signal! came from the object 2MASS 19281982-2640123Īstronomer Alberto Caballero said that the signal could come from a sun-like star located at a distance of 1800 light-years in the constellation Sagittarius. Now, perhaps, the exact source of the alleged broadcast of “aliens”, discovered almost half a century ago, has been determined. Researchers have expressed different ideas about the origin of this message: from intelligent beings to a passing comet. Signal and the longest-running SETI (Search for ExtraTerrestrial Intelligence) project entered into the Guinness Book of Records. Known to this day as the “mysterious Wow! signal”, it was caught by a radio telescope on the night of August 15, 1977. The Wow! signal is considered the best candidate radio signal for the SETI project to search for extraterrestrial civilizations.
