The James Webb Space Telescope has found a strange alien world shrouded in clouds of sand-like silicate grains.

The exoplanet discovery, described in a new paper as the first detection of its kind, was made by the James Webb Space Telescope's NIRSpec and MIRI instruments. In the data, astronomers spotted evidence of silicate-rich clouds around a brown dwarf nearly 20 times the size of Jupiter. The finding confirms some earlier theories about these odd planet-like worlds.
