Amateur Astronomer Finds Possible Source of Wow! Signal

A recent paper by amateur astronomer and YouTuber Alberto Caballero identifies a possible source of the Wow! signal, the curious cosmic radio blitz recorded in 1977 that expedited the search for extraterrestrial intelligence and puzzles experts to this day. Looking for “sun-like stars that might host an exoplanet capable of supporting intelligent life” in the signal’s celestial region, Caballero scanned ESA’s 1.3 billion star-strong Gaia database and found a potential match: “This candidate source, which is named 2MASS 19281982-2640123, therefore becomes an ideal target to conduct observations in the search for potentially habitable exoplanets.”
