James Webb Space Telescope forecasts clouds of melted rock on this blisteringly hot exoplanet

An illustration shows a hot Jupiter planet tidal locked to its star resulting in blisteringly hot dayside and a cooler nightside.

The James Webb Space Telescope (JWST) has performed a weather report for a distant planet.

The powerful space telescope forecasts extreme wind speeds, blisteringly hot temperatures and blankets of rock clouds for the world, named Wasp-43b. As such, the extrasolar planet, or "exoplanet," demonstrates just how strange alien planets outside the solar system can be.
