The James Webb Space Telescope identifies LHS 1140 b, a nearby "super-Earth" exoplanet, potentially the first known ocean world outside the Solar System.

The James Webb Space Telescope reveals a nearby exoplanet, LHS 1140 b, could be the first known ocean world outside our Solar System. Located 48 light-years away, LHS 1140 b is one of the few exoplanets in the "Goldilocks zone," where conditions could support liquid water. Initially considered a "mini-Neptune," new observations confirm LHS 1140 b is a rocky "super-Earth."
