The James Webb Space Telescope (JWST) has released one of its largest images to date, revealing a vast star field in the IC 348 region. Within this image, JWST identified several 'dark dwarfs' with masses equivalent to two Jupiters, which are lighter than previously predicted by theoretical models. These celestial objects do not heat sufficiently to initiate hydrogen fusion, thus failing to become full-fledged stars. This discovery could lead to a re-evaluation of current star formation processes.
