The James Webb Space Telescope has made a groundbreaking discovery, finding what may be the first-ever evidence of "failed stars" or brown dwarfs beyond our galaxy. Brown dwarfs are objects that are larger than planets but smaller than stars and don't have enough mass to sustain nuclear fusion. The observation suggests that these failed stars form in a similar way as regular stars, but just can't capture enough mass to become fully-fledged stars.
