An article published in the journal “The Astrophysical Journal” describes a new research on the possible climate existing on the seven rocky planets of the star TRAPPIST-1’s system. A team of astronomers coordinated by the University of Washington (UW) used updated climate models to try to understand what kind of atmospheres they can have as a result of environmental evolution based on the observations collected. The result is that the planet TRAPPIST-1 e is the one most likely to have liquid water on its surface.
