"Exoplanet with Rotten Egg Odor and Glass Rain Discovered"

Scientists using the James Webb Space Telescope have detected hydrogen sulfide, a molecule that smells like rotten eggs, in the atmosphere of the exoplanet HD 189733b. This discovery marks the first time hydrogen sulfide has been found outside our solar system and provides new insights into the atmospheric composition of exoplanets. HD 189733b, a "hot Jupiter" known for its extreme weather, including glass rain and high temperatures, also contains water, carbon dioxide, and carbon monoxide. The findings, published in Nature, enhance our understanding of exoplanet formation and atmospheric chemistry.
