Amateur astronomer Alberto Caballero finds possible source of Wow! signal
Amateur astronomer and YouTuber Alberto Caballero, one of the founders of The Exoplanets Channel, has found a small amount of evidence for a source of the notorious Wow! signal.
Back in 1977, astronomers working with the Big Ear Radio Telescope-at the time, situated in Delaware, Ohio-recorded a unique signal from somewhere in space. It was so strong and unusual that one of the workers on the team, Jerry Ehman, famously scrawled the word Wow! on the printout. Despite years of work and many man hours, no one has ever been able to trace the source of the signal or explain the strong, unique signal, which lasted for all of 72 seconds. Since that time, many people have suggested the only explanation for such a strong and unique signal is extraterrestrial intelligent life.
Caballero began searching the publicly available Gaia database for just such a star. The Gaia database has been assembled by a team working at the Gaia observatory run by the European Space Agency. Launched back in 2013, the project has worked steadily on assembling the best map of the night sky ever created. To date, the team has mapped approximately 1.3 billion stars.
In studying his search results, Caballero found what appears to fit the bill-a star (2MASS 19281982-2640123) that is very nearly a mirror image of the sun-and is located in the part of the sky where the Wow! signal originated. He notes that there are other possible candidates in the area but suggests his candidate might provide the best launching point for a new research effort by astronomers who have the tools to look for exoplanets.
