Webb Finds Failed Stars at Two Jupiters

Updated: 2026.10.02 2H ago 1 sources
The James Webb Space Telescope has identified brown dwarfs in the IC 348 star‑forming region with masses as low as roughly two times Jupiter’s mass—far lighter than prior theoretical lower limits. These objects are cool and faint, detected by JWST’s near‑infrared camera, and at least one shows signs of a circum‑object disk, blurring the line between planets and stars. — If confirmed and common, such super‑light brown dwarfs force revisions to star and planet formation models, affect how we classify exoplanets versus failed stars, and reshape priorities for observational programs and public science communication.
