JWST Finds Atmospheric Evidence on Distant Lava Exoplanet HD 3167 b

The James Webb Space Telescope has provided strong evidence of an atmosphere around HD 3167 b, a rocky super-Earth 154 light-years away. This discovery is notable given the planet's extreme heat and rapid orbit, offering new insights into how rocky planets, including early Earth, might retain atmospheres. Classified as a 'lava world,' it completes an orbit in one Earth day, expanding the list of known rocky exoplanets with atmospheres and being the coldest lava world found with such evidence.
