You all should have known by now about the discovery and what not.
In 2015, astronomers discovered three Earth-sized planets orbiting the dwarf star. The team, led by Michaël Gillon at the University of Liège in Belgium, detected the planets using transit photometry with the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) at the La Silla Observatory in Chile. On 22 February 2017, astronomers announced four additional exoplanets around TRAPPIST-1. Besides TRAPPIST, this work utilized the Very Large Telescope at Paranal and the NASA Spitzer Space Telescope, among others, and brought the total number of planets orbiting the star to seven, of which at least three, and possibly all, are in its habitable zone.
