Hunting for aliens in the galaxy’s most promising neighborhood

TRAPPIST-1 is a red dwarf star located about 40 light years away that hosts seven Earth-sized rocky planets, with at least three orbiting in the habitable zone where liquid water could potentially exist. This makes it one of the most solar system-like exoplanet systems discovered, with TRAPPIST-1e considered among the best potentially habitable exoplanets. The system’s proximity and multiple potentially habitable worlds make it an ideal target for searching for technological civilizations.
