Webb Data Reveals Hot Jupiter Exoplanet with Hydrogen Sulfide and Rotten Egg Smell

Jul 8, 2024, 03:03 PM

Recent data from the James Webb Space Telescope (JWST) has revealed that a nearby exoplanet, often referred to as the 'Rotten Egg Planet,' contains trace amounts of hydrogen sulfide. This discovery, which was made in collaboration with Johns Hopkins University and published in Nature, suggests that the planet emits a smell similar to rotten eggs. The exoplanet, categorized as an extreme 'hot Jupiter,' also experiences violent glass storms. These findings, based on Webb data, contribute to the growing body of evidence regarding the chemical composition of exoplanets and the potential for primitive life forms in the universe. This marks a significant scientific breakthrough.
