JWST Detects Elusive Trihydrogen Molecule (H3+) for First Time

The James Webb Space Telescope (JWST) has achieved a significant milestone by detecting the trihydrogen molecule (H3+), a cosmic entity theorized by physicists four decades ago but never before observed. This discovery, made in stellar nurseries like Herbig-Haro 168, is anticipated to transform understanding of star formation and the universe's chemical evolution. JWST's sensitivity allowed for the identification of 26 distinct spectral lines of trihydrogen with high statistical certainty.
