Knowing that the Big Ear telescope's two receivers were pointing in the direction of the constellation Sagittarius on the night of the Wow! Signal, Caballero decided to search through a catalog of stars from the European Space Agency's Gaia satellite to look for possible candidates. "I found specifically one sun-like star," he said, an object designated 2MASS 19281982-2640123 about 1,800 light-years away that has a temperature, diameter and luminosity almost identical to our own stellar companion. Caballero's findings appeared May 6 in the International Journal of Astrobiology. "I think this is perfectly worth doing because we want to point our instruments in the direction of things we think are interesting," Rebecca Charbonneau, a historian who studies SETI at the Harvard-Smithsonian Center for Astrophysics and who wasn't involved in the work, told Live Science. "There are billions of stars in the galaxy, and we have to figure out some way to narrow them down," she added.
But she wonders if looking for only sun-like stars is too limiting. "Why not just look at a bunch of stars?" she asked.
