New research using Nasa’s powerful JWST telescope has identified a planet 41 light years away which may have an atmosphere. The planet is within the “habitable zone”, the region around a star where temperatures make it possible for liquid water to exist on the surface of a rocky world. This is important because water is a key ingredient that supports the existence of life.
If confirmed by further observations, this would be the first rocky, habitable zone planet that’s also known to host an atmosphere. The findings come from two new studies published in the journal Astrophysical Journal Letters.
The habitable zone is partly defined by the range of temperatures generated by heat from the star. The zone is located at a distance from its star where temperatures are neither too hot nor too cold (leading to it occasionally being nicknamed “the Goldilocks zone”).
