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...

James Webb surpasses its previous record for the furthest galaxy ever seen.

James Webb's scientific operations have only been underway for a few days, but the massive infrared observatory has already surpassed its previous record for the farthest distant galaxy ever seen. A team discovered an observation of a galaxy 400 million years after the Big Bang last week. A galaxy was discovered this week, only 235 million years after the Big Bang, according to a new investigation. It is 35 billion light-years from our planet. James Webb looks farther than ever into the cosmos. The University of Edinburgh scientists that made the recent finding assembled a list of early galaxies discovered by Webb to study the luminosity function of galaxies that originated soon after the Big Bang. The unexpected discovery was a happy accident because they hadn't intended to observe...
