JWST Observes Predicted H₃⁺ Light, Validating Decades-Old Physics Theory

The James Webb Space Telescope (JWST) has detected the "forbidden" rotational light of the H₃⁺ molecule, a phenomenon theorized by physicists 40 years ago but unobserved until now. This detection confirms long-standing theoretical calculations regarding the molecule's behavior and highlights the JWST's exceptional mid-infrared sensitivity. The finding represents a significant validation in astrophysics.
