It’s still possible that one of the other candidates could turn out to be a better fit, but as of now, 2MASS 19281982-2640123 is the one that’s of special interest. As for the other candidates, he said, astronomers need more data about their luminosities or sizes. Right now, according to Caballero, 2MASS 19281982-2640123 is the strongest candidate star for being the source of the Wow! signal. Amateur astronomer Alberto Caballero of The Exoplanets Channel and the Habitable Exoplanet Hunting Project wrote the new paper on a sunlike star that might be the source of the Wow! signal. It is the best candidate found so far for the origin of the Wow! signal. 2MASS 19281982-2640123, a sun-like star 1,800 light-years away in the constellation Sagittarius. It is an identical twin to our sun, with the same temperature, radius, and luminosity. This star sits in the constellation of Sagittarius at a distance of 1,800 light-years. The only potential sunlike star in all the WOW! signal region appears to be 2MASS 19281982-2640123. His search of Gaia data revealed 66 potential candidate stars, but one in particular stood out: 2MASS 19281982-2640123, a sunlike star located in the direction of the constellation Sagittarius, along our line of sight to the center of our Milky Way galaxy. So far, the only intelligent life we know is here on Earth, so it’s logical to look for extraterrestrial intelligence around stars similar to our sun. Makes a great gift!įor this study, Caballero focused on sunlike stars, from mid-K to G-type (our sun is a G-type star).

Using data from Gaia’s first and second data releases, Caballero searched for sunlike stars in the region of the sky from which the Wow! signal emanated. The finding is based updated data about our Milky Way galaxy from ESA’s Gaia space observatory, which is in the process of creating a cool new 3-D map of our galaxy. On November 19, The Physics arXiv Blog at also announced Caballero’s finding. It’s a sunlike star – labeled 2MASS 19281982-2640123 – 1,800 light-years away, in the direction of the center of our Milky Way galaxy.
He might even have identified the specific star of origin. In it, he said he has narrowed down the source of the Wow! signal. On November 8, 2020, the non-peer-reviewed, open-access repository of electronic preprints arXiv published a scientific paper by Caballero. He’s a founder of The Exoplanets Channel on YouTube and coordinator of the Habitable Exoplanet Hunting Project, which, earlier this year, announced GJ 3470 c, the first exoplanet candidate fully discovered by amateur astronomers. Enter amateur astronomer Alberto Caballero. It still hasn’t been adequately explained. Known as the Wow! signal, it was heard only once and never again. In August 1977, astronomers detected an unusual radio signal coming from deep space that’s been the subject of debate ever since. Image via Big Ear Radio Observatory/ North American Astrophysical Observatory. It was a leading candidate for an extraterrestrial radio signal, but was never heard again. The famous Wow! signal, detected by the Big Ear Radio Observatory in Ohio on August 15, 1977.
