JWST Detects Possible Atmosphere on Distant Lava Exoplanet

The James Webb Space Telescope has gathered evidence suggesting HD 3167 b, a rocky lava world 154 light-years away, may possess an atmosphere. The planet's dayside emitted less infrared light than expected for bare rock, indicating heat absorption by an atmospheric layer. This super-Earth, orbiting its star in 23 hours, is the coldest lava world found with atmospheric evidence, challenging existing exoplanet models.
