A Planet's Rotation Revealed Its Fiery Secrets

Astronomers studied WASP-121 b, a gas giant always facing its star with one side. As the planet transited the star, they detected changes in light absorption: the eastern limb was hotter than the western, which destroys water and leaves carbon monoxide. This opens a method for scanning weather on su
