Webb studied the planet HAT-P-26 b and found water, carbon dioxide, and sulfur dioxide in its air. Previously, SO₂ had only been spotted on scorching hot giants or chilly sub-Neptunes; now it's clear that photochemistry works across a wide temperature range. A trend emerged: the higher the atmospher

The James Webb Space Telescope has peered into a previously unseen world: the atmosphere of the giant planet WD 1856 b, orbiting a white dwarf. The transit spectrum from 0.5 to 5.0 μm revealed hydrocarbons, including methane with a significance of 17:1 to 30:1, thick aerosols, and thermal glow from
