According to a new analysis from scientists at the University of Nottingham in England we don’t have a lot of alien company. On June 15, two researchers published a paper in the Astrophysical Journal arguing that the Milky Way — which sports an estimated several hundred billion stars — could host as few as 36 alien societies. That’s a surprisingly tiny number, although the authors also make a second, more generous analysis in which they say that the count might be as many as a thousand.
