JWST Discovers Tiny Brown Dwarf Just 3-4x Jupiter’s Mass: A Cosmic 'Failed Star' in the Making
The James Webb Space Telescope (JWST), humanity’s most powerful observatory, has uncovered the smallest brown dwarf ever detected—a celestial "failed star" with a mass just 3 to 4 times that of Jupiter. This diminutive object, located in the IC 348 star cluster within the Perseus constellation (~1,000 light-years from Earth), challenges long-held theories about the minimum mass required for star formation. The discovery, led by astronomers Kevin Luhman (Pennsylvania State University) and Catarina Alves de Oliveira (ESA), reveals a cosmic frontier where stars and planets blur into ambiguity.
