✨ 10 years ago today, our small TRAPPIST telescope in Chile spotted the first planet transiting the star later named TRAPPIST-1.

7 Earth-sized worlds followed — 3 in the habitable zone 🌍

Why not make Sept 17 = #TRAPPIST1Day? 🚀🔭

Why a Hint of an Atmosphere on this Alien Planet is Such a Big Deal A monumental sign of an atmosphere on TRAPPIST-1e could be the precursor to finally finding a living world around another star

First #JWST results for TRAPPIST-1e are out 🚀
