Direct Evidence of Exoplanet Volcanic Activity Found

The James Webb Space Telescope provided the first direct spectroscopic evidence of active volcanic activity on an exoplanet in 2025, detecting sulfur dioxide and volcanic gas signatures on moon candidates orbiting a nearby star system. The discovery expanded scientists' understanding of geological activity across planetary systems and opened new avenues in the search for habitable environments. The research was published in The Astrophysical Journal Letters.
