The James Webb Space Telescope reveals chemical details in the atmosphere of the exoplanet WASP-39b.

The planet, which is about 700 light-years from Earth, is covered in thick clouds containing sulfur and silicates. The chemical interacts with light from the parent star and produces sulfur dioxide.

Experts say the chemical reaction is similar to the formation of ozone in the Earth’s atmosphere.
