An estimated 1,715 nearby stars may have been in a position to see Earth in the past 5,000 years, according to a paper in Nature. 29 potentially habitable worlds orbiting some of these stars could have both seen Earth and received human-made radio waves.
キャッチーな感じで言うと、我々の存在はすでに、人間のような知的生命体にばれているかも知れない、とのことらしいです。
