JWST Finds New World Of Turbulent Silicate Clouds
I can't resist this story, even though it's not what you would call a prediction by science fiction authors. Quite.
The spectra showed signs of clouds made of silicates, which periodically rain down into the depths of the planet, moving about in an atmosphere as hot as a flame, around 1,500 degrees Fahrenheit (815 degrees Celsius). Silicate clouds have no equivalent here on Earth, other than maybe being in a cloud of hot sand.

As science fiction fans know, the small world of Ceti Alpha V from Star Trek: The Wrath of Khan is indeed such a world of whirling sand. Although I couldn't quite find the video I wanted, I kind of like this one. Turn the sound up.
The pioneering observatory just peered directly into the atmosphere of a giant exoplanet with two suns (like Tatooine from "Star Wars") known as VHS 1256 b — and found a roiling world with turbulent clouds made of silicates, similar to sand here on Earth, as announced in a recently published article in Astrophysical Journal Letters.
