New Model: Nearby Exoplanet TRAPPIST-1e May Be Just Right for Life

Tucked between a boiled-away desert and a giant snowball, an alien world called TRAPPIST-1e may be the only habitable planet in a newly discovered batch of seven, according to a new climate model. One of the first scientists to model the worlds' potential climates in depth was Eric Wolf, a researcher at University of Colorado, Boulder. Wolf modeled three planets around TRAPPIST-1 and tested different potential atmospheres to see whether any let liquid water exist on a planet's surface.
