James Webb has observed a brown dwarf just 72 light-years away, discovering sandy clouds within its atmopshere.
James Webb has spotted a strange alien planet with sand-filled clouds. The exoplanet, which is a brown dwarf, was originally discovered in 2016. It’s known as VHS 1256 b and orbits two small red dwarf stars. Astronomers were puzzled over the exoplanet’s strange reddish glow, but James Webb gave them a better view of the stellar discovery.Brown dwarfs are intriguing stellar objects. These planets aren’t big enough to turn into stars, but they’re just too big to be regular planets.
This belief appears to have been confirmed thanks to observations made by the James Webb space telescope. By looking at the brown dwarf, astronomers were able to detect thick clouds of sand-like silicate grains. The space telescope also picked up traces of water, carbon monoxide, carbon dioxide, methane, sodium, and potassium.servers. The paper has yet to be published and hasn’t been peer-reviewed yet. They say that the brown dwarf James Webb observed is still small for that type of planet.
