The TRAPPIST project was only a forerunner for a more concerted search for exoplanets around dwarfs called SPECULOOS, which will rely on four 1 - meter telescopes currently being installed at ESO's Paranal Observatory in Chile. (sciencemag.org)
PLATO will search for exoplanets using what is known as the transit method, which simply involves measuring the dimming of the light from a star as a planet passes in front of it. (sciencemag.org)
This solution paved the way for the follow up K2 mission, which is still ongoing as the spacecraft searches for exoplanet transits. (sciencedaily.com)
