Remarkable finding. JWST found mysterious dust clouds in the exoplanet WASP-23b's atmosphere.

"This artist’s concept shows what the hot gas-giant exoplanet WASP-43 b could look like. WASP-43 b is a Jupiter-sized planet circling a star roughly 280 light-years away, in the constellation Sextans. The planet orbits at a distance of about 1.3 million miles (0.014 astronomical units, or AU), completing one circuit in about 19.5 hours. Because it is so close to its star, WASP-43 b is probably tidally locked: its rotation rate and orbital period are the same, such that one side faces the star at all times." (ScitechDaily, Remarkable Webb Telescope Find: Mysterious Dust Clouds on an Alien World)

"Temperature measurements based on the amount of 5- to 12-micron mid-infrared light emitted by the planet show that the nightside is probably covered in thick, high clouds. Spectroscopy measurements indicate the presence of water vapor on both the dayside and nightside. But because it is too hot for liquid water to exist, the clouds are probably made of tiny mineral grains instead of water droplets. A surprising lack of methane on the nightside suggests that strong eastward winds are mixing atmospheric gases around the planet. This illustration is based on new data gathered by Webb’s Mid-Infrared Instrument (MIRI) as well as previous observations from other ground- and space-based telescopes, including Hubble and Spitzer.

The exoplanet WASP 43b is a locked and hot world. It's about twice a Jupiter-size gas giant that orbits spectral type K-star WASP 43. The remarkable thing is that the WASP 42 is hotter and heavier than M-type stars. And WASP 43b orbits that orange star in 19 hours. 

The WASP 43 is a young and active star. The surface temperatures of K-type main sequence stars are between 3400-4900C. And the young stars are always active. Near young stars are many ice and rocks that can cause meteorite bombardment.

Of course, the WASP 43b is a large gas giant. But the active star near a large planet can cause a situation that in asteroid bombardment along with high-temperature plasma impulses can overheat the planet's atmosphere. The overheating means that the atmosphere turns hotter than the planet's core. Then that high-temperature ionized atmosphere can send energy impulses to the planet's core. And then that energy could rip the planet in pieces. 

If there are anions and ions in the planet's atmosphere, the high temperature along with affecting positive and negative particles and with high pressure can form fusion in the planet's atmosphere. That thing can send energy impulses to the planet's core. And break it. The thing that keeps the planet in its form is massive gravity. And energy impulses from the planet's shell can destroy its core.

Because WASP 43b is near quite a hot and young star, its position near the star causes a situation where lots of objects travel over its trajectory. The question is how this planet remains in one piece. Maybe its magnetic fields drive particles around it. 

Or maybe, the plasma that forms a standing wave between the planet and its star destroys all incoming material objects. And drives plasma that the star sends around it, denying their straight effect on the planet, and its atmosphere. The dust in its atmosphere can be remnants of destroyed comets and asteroids.
