Study finds exoplanet TRAPPIST-1e is unlikely to have a Venus- or Mars-like atmosphere

In the search for habitable exoplanets, atmospheric conditions play a key role in determining if a planet can sustain liquid water. Suitable candidates often sit in the "Goldilocks zone," a distance that is neither too close ...
