Credit: NASA/JPL-Caltech ...Caption: NASA’s JWST made the first identification of sulfur dioxide in an exoplanet’s atmosphere. Its presence can only be explained by photochemistry – chemical reactions triggered by high-energy particles of starlight. Photochemistry is essential to processes on Earth key to life like photosynthesis and the generation of our ozone layer.The hypothesis is that the haze is effective in radiating thermal energy from collisions back to space; this could be tested by the JWST. Wong emphasized that the chemical and chemical-engineering communities can contribute to the study of Pluto by conducting laboratory studies that, for example, measure sticking coefficients and the …
