JWST Discovers Surprising Exoplanet Atmospheres.
TL;DR
The James Webb Space Telescope has discovered that the atmosphere of exoplanet HD149026b is super-abundant in the heavier elements carbon and oxygen, far above what scientists would expect for a planet of its mass. The carbon-to-oxygen ratio is elevated relative to our solar system, which could provide insight into planet formation and an important first step toward obtaining similar measurements for a large sample of exoplanets in order to search for statistical trends.
