Nearby super-Earth has a sulfur-rich atmosphere, Webb observations suggest

Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) in Baltimore, Maryland and elsewhere have conducted transmission spectroscopy of a nearby super-Earth exoplanet known as L98-59 d. Results of these observations, available in a research paper published August 28 on the pre-print server arXiv, suggest that the planet has a sulfur-rich atmosphere.
