TRAPPIST-1 planets provide clues to the nature of habitable worlds

To determine the composition of the TRAPPIST-1 planets, the team used a unique software package that uses state-of-the-art mineral physics calculators. The software, called ExoPlex, allowed the team to combine all of the available information about the TRAPPIST-1 system, including the chemical makeup of the star, rather than being limited to just the mass and radius of individual planets.
