University of Michigan researchers in an international team revealed that a rocky planet in a distant star’s “habitable zone” may have an atmosphere. Potentially, this means it could have the requisite ingredients for supporting life as we know it.
In two separate studies published in the Astrophysical Journal Letters, researchers have shed new light on an Earth-sized exoplanet 40 light-years away where liquid water might exist on its surface. That would only be possible if an atmosphere is present on this planet, dubbed TRAPPIST-1 e. Still, there’s enough uncertainty that some mystery still shrouds this exoplanet, a planet outside our solar system.
