Has the source of the famous 1977 WOW! signal being revealed? Believed to have originated within the constellation of Sagittarius from a star-like sun.
In 1977 whilst listening to radio signals via the now decommissioned Big Ear telescope in Ohio, U.S, astronomer Jerry R. Ehman, famously wrote "WOW!" on a rudimentary computer readout of numbers and letters, circling with a pen"6EQUJ5". Which indicated a signal detected within the lower 1420.4056 megahertz band for hydrogen signals, that as quoted by Ehman:
"Since hydrogen is the most abundant element in the universe, there is good logic in guessing that an intelligent civilization within our Milky Way galaxy desirous of attracting attention to itself might broadcast a strong narrowband beacon signal at or near the frequency of the neutral hydrogen line".
Which means that the WOW! signal pieced through the background noise of the Universe, therefor making in more so a candidate for an intelligent civilization.
Forty three years later, in 2020 amateur astronomer Alberto Caballero has hypothesized that the WOW! signal may have come from a sun-like star within the constellation of Sagittarius, he has proposed with a peer preview paper on arXiv that the star named 2MASS 19281982-2640123 is, at this point in time, to be the likely source. To which Caballero has since speculated that we should be looking at sun-like stars as places that intelligent life maybe connected to or at least their planets orbit around.
The WOW! signal, although a one off abnormality in our search for intelligent lifeform/s in our Galaxy and greater Universe, is still mostly a mystery. But, Caballero's study that the origins of the WOW! signal point to a life giving sun and a possible exoplanet that orbits it, may offer a tantalizing answer.
