Exoplanet HD 189733 b accommodates hydrogen sulfide, in step with new analysis. July 9, 2024, 7:30 PM ET• 4 min readScientists made a thrilling — and smelly — announcement a couple of within sight exoplanet this week, discovering {that a} planetary frame with a likeness to Jupiter smells of rotten eggs.Examining information collected through the James Webb Area Telescope, scientists found out that an exoplanet named HD 189733 b accommodates hydrogen sulfide, a drab fuel emitted through decaying natural topic with a powerful, egg-like scent.Along with hydrogen sulfide, researchers discovered carbon dioxide, oxygen, water and heavy metals within the distinctive exoplanet’s surroundings, in step with the learn about printed in Nature on Monday.”Hydrogen sulfide is a significant molecule that we did not know used to be there. We predicted it might be, and we comprehend it’s in Jupiter, however we hadn’t in reality detected it out of doors the sun gadget,” Guangwei Fu, an astrophysicist at Johns Hopkins, who led the analysis, mentioned in a press unlock.Exoplanet HD 189733 b circles its house celebrity 13 occasions nearer than Mercury orbits the solar. Roberto Molar Candanosa/Johns Hopkins UniveristyExoplanet HD 189733 b used to be to begin with found out in 2005 and is situated roughly 65 mild years from Earth within the constellation Vulpecula, in step with the learn about.Identified for excessive temperatures and “vicious climate,” scientists dubbed the exoplanet as “scorching Jupiter” as it has “sizzling temperatures of one,700 levels Fahrenheit and is infamous for vicious climate, together with raining glass that blows sideways on winds of five,000 mph,” in step with the learn about.”We are not searching for existence on the earth as a result of it is approach too scorching, however discovering hydrogen sulfide is a stepping stone for locating this molecule on different planets and gaining extra working out of the way various kinds of planets shape,” Fu mentioned.Taking a look to the longer term, Fu mentioned his analysis staff will observe sulfur in additional exoplanets to investigate if the presence of top ranges of the chemical compound is said to their placement in house.”We need to know the way all these planets were given there, and working out their atmospheric composition will lend a hand us solution that query,” Fu mentioned.
