Exoplanet HD 189733b, located only 64 light-years from Earth, has long intrigued astronomers because of its scorching temperatures, screaming winds and sideways rain made of glass. Now, data from the James Webb Space Telescope has revealed another intriguing feature of the planet: It smells like rotten eggs, CNN writes.
Researchers studying HD 189733b’s atmosphere used Webb’s observation to spot trace amounts of hydrogen sulfide — a colorless gas that releases a strong sulfuric stench and has never been spotted beyond our solar system.
Scientists first discovered HD 189733b in 2005 and later identified the gas giant as a “hot Jupiter”.
