Astronomers left puzzled by high-altitude clouds forming on young planet

Experts say thick slabs of cloud in YSES-1 system could consist of mineral dust and iron, which would rain down

Should humans ever venture to a particular planet that circles a sun-like star in the constellation of the fly, they would do well to keep an eye on the weather.

The thick slabs of cloud that blot the planet's skies are mostly made from mineral dust, but astronomers suspect there may be iron in them, too, which would rain down on the world below when the clouds break.
