Astronomers have detected active chemistry in an exoplanet for the first time. In papers published Tuesday, astronomers said James Webb Space Telescope observations of the exoplanet WASP-39b showed evidence of patchy clouds and sulfur dioxide, suggesting photochemical reactions in its atmosphere that would produce it. The composition of the planet's atmosphere suggests it formed further from its host star and migrated inwards to its current location.
