Using data from James Webb’s early release, a new brown dwarf was found.

With the aid of the James Webb Space Telescope, a global team of scientists has discovered a brand-new, faint, far-off, and cold brown dwarf (JWST). The recently found object, designated GLASS-JWST-BD1, is approximately 31 times as massive as Jupiter. On July 29, a paper describing the discovery was published on arXiv.org. Brown dwarfs are thought to be transitional objects between planets and stars. They are generally agreed to be substellar objects with masses between 13 and 80 Jupiter masses. Brown dwarfs of the T dwarf subtype have effective temperatures ranging from 500 to 1,500 K. They are the least bright and coolest substellar objects that have been found so far. Studying T dwarfs may help astronomers better comprehend objects near the disputed planet/star divide, such as la...
