By constraining the age of the seven-planet system, we can better our understanding of its habitability
The orbital period of the TRAPPIST-1 system’s most remote planet, TRAPPIST-1h, has been uncovered
The system has both the largest number of Earth-sized planets yet found and the largest number of worlds that could support liquid water on their surfaces
Similar in size and temperature to Venus and Earth, the exoplanets are the best targets so far in our search for life
