The exoplanet LHS 1140 b, discovered in 2017, may be an “eyeball” planet with a liquid ocean surrounded by ice, making it a candidate for habitability. Initially thought to be a “mini-Neptune,” new findings suggest it is icier and wetter, potentially supporting life. The James Webb Space Telescope’s observations indicate it could be our best chance to confirm liquid water on an alien world. Charles Cadieux, an astrophysicist at the University of Montreal, highlights its significance in the search for habitable exoplanets.
