Four light-years from Earth, the triple-star system of Alpha Centauri has long been humanity's closest celestial neighbor — a bright point in the southern sky that ancient eyes mistook for one star and modern instruments have revealed to be three, each with worlds of its own. Recent decades have brought the extraordinary discovery of at least five planets orbiting these stars, including a super-Earth sitting within the habitable zone of Proxima Centauri, the nearest star to our sun. These findings invite a quiet but profound reckoning: that Earth-like worlds may be woven throughout the galaxy,
