Simple Exoplanet Calculation Describes Alien Atmospheres in a Flash

A new mathematical formula predicts the ratio of particular molecules in the atmospheres of far-off planets, letting researchers more easily tell when something unusual is happening there. The new method is tailor-made to predict the ratios of nine important atmospheric molecules built from carbon, hydrogen, oxygen and nitrogen, so researchers can quickly learn what combination of molecules should be found on a high-temperature planet without using complicated simulations. The first hint of life
