TRAPPIST-1e is the fourth planet in the red dwarf star system TRAPPIST-1, and it orbits firmly within the star's habitable zone.
A team of researchers has identified a possible atmosphere around an Earth-sized planet.
The researchers, from the University of St Andrews, have today published two separate papers on planet TRAPPIST-1e.
They say liquid water, in the form of a global ocean or icy expanse, might exist on its surface.
Published in the Astrophysical Journal Letters, researchers say the James Webb Space Telescope (JWST) is a step closer to solving whether or not the planet has an atmosphere.
TRAPPIST-1e is the fourth planet in the red dwarf star system TRAPPIST-1, which is located in the constellation Aquarius, and is around 40 light years away from Earth.
The planet orbits firmly within the star's habitable zone, and has a mass comparable to that of Earth.
This is the first search for an atmosphere and surface habitability on the planet with the JWST.
Planet 1e is of particular interest because the presence of liquid water is theoretically viable, but only if the planet has an atmosphere.
The initial results indicate several potential scenarios, including the possibility of an atmosphere.
