New Insight Into TRAPPIST 1 Planets
Two new, but separate, studies provide fresh insight into planets orbiting the nearby red dwarf star TRAPPIST-1. One of the studies, published in the journal Nature Astronomy, suggests the atmospheres of at least three of the seven TRAPPIST-1 exoplanets found so far do not seem to be as hydrogen-rich as our solar system’s gas giant […]
