Astronomers identified the new substellar object in a JWST image of galaxy cluster Abell 2744. The brown dwarf GLASS-JWST-BD1 is a single object more than 2 thousand light years away. It has about 30 jupiter masses (0.03 solar mass).
Brown dwarfs are often found in pairs. However their low gravity is causing them to break away from each other more often than binary stars. Astronomers now found the brown dwarf pair with the widest separation of 129 AU (about 4 times the distance between Neptune and the Sun).
Astronomers recently weighed a young exoplanet orbiting star HD 114082. Together with its radius it allowed them to calculate its density, and it is too dense to be explained by current models.
