The universe never ceases to amaze us with its bizarre and extreme wonders. One such wonder is the exoplanet HD 189733b, a scorching hot gas giant discovered in 2005. Already known for its striking cobalt blue color and molten glass rain that blows sideways in fierce atmospheric winds, this planet has just added another peculiarity to its resume: the presence of hydrogen sulfide, the chemical compound that gives rotten eggs their distinct stench.
A Smelly Revelation
Recent data from the James Webb Space Telescope has revealed a trace amount of hydrogen sulfide in HD 189733b's atmosphere. This is the first time this chemical has been detected on any exoplanet. "Yes, the stinky smell would certainly add to its already infamous reputation. This is not a planet we humans want to visit, but a valuable target for furthering our understanding of planetary science," said Guangwei Fu, an astrophysicist at Johns Hopkins University and lead author of the study published in Nature.
A Scorching Hot Jupiter
HD 189733b falls into the category of "hot Jupiters" – gas giants similar to Jupiter but much hotter due to their close proximity to their host stars. This particular planet orbits its star 170 times closer than Jupiter does to the sun, completing one orbit every two days compared to Jupiter's 12-year orbit. The temperature on the side of the planet facing its star reaches a blistering 1,700 degrees Fahrenheit (930 degrees Celsius).
"They are quite rare," Fu said of hot Jupiters. "About less than one in 100 star systems have them." Located 64 light-years from Earth in the constellation Vulpecula, HD 189733b is considered to be in our neighborhood within the Milky Way galaxy.
A Unique Opportunity for Study
The relatively close distance of HD 189733b makes it an excellent candidate for detailed study. "The close distance makes it bright and easy for detailed studies. For example, the hydrogen sulfide detection reported here would be much more challenging to make on other faraway planets," Fu explained.
The star it orbits is smaller and cooler than our sun and is part of a binary system, meaning it is gravitationally bound to another star. Observations from the James Webb Space Telescope, operational since 2022, allow for more thorough examinations of exoplanet atmospheres due to its ability to observe a wider wavelength range than earlier space telescopes.
More Similar to Jupiter Than We Thought
"Our research finds that HD 189733b is more similar to Jupiter than previously known," said Luis Welbanks, an astrophysicist at Arizona State University and co-author of the study. "This planet is very much like Jupiter, but just hotter." Like Jupiter, HD 189733b has trace amounts of hydrogen sulfide in its atmosphere. The planet is about 10% larger than Jupiter in both diameter and mass.
In addition to detecting hydrogen sulfide, Webb's observations have confirmed the presence of water and carbon dioxide in HD 189733b's atmosphere, corroborating earlier data. This smelly and scorching world continues to be a fascinating subject for astronomers, offering valuable insights into the complexities of planetary science.
