A combustion engineer solved one of JWST’s biggest mini-Neptune mysteries — and the answer is diesel exhaust

A UChicago combustion engineer recognized in JWST's mysterious mini-Neptune spectra the same opacity signature he had seen in diesel engines for years. The explanation: the most common planet type in the galaxy may be producing soot in its deep atmosphere via the same hydrocarbon chemistry that powers combustion engines on Earth.

Many planets in the universe may be hazed in clouds of soot, according to a new study by University of Chicago scientists. According to the analysis, high temperatures and crushing pressures on these planets could combine to make 'soot factories,' much like combustion engines here on Earth, which shroud the planets in smog.
