HD 189733b is a scorching hot gas giant exoplanet, slightly larger than Jupiter, located about 63-64 light-years away in the Vulpecula constellation. It has a striking cobalt blue hue, violent atmospheric conditions with winds up to 2 km/s (5,000 mph), temperatures around 930°C (1,700-1,800°F), and is believed to have molten glass rain driven sideways by fierce winds. It also appears to have a planet-sized smell of rotten eggs.
The James Webb Space Telescope has detected the presence of hydrogen sulfide (which gives off a rotten egg smell), water, carbon dioxide, carbon monoxide, and heavy metals in the atmosphere of the exoplanet HD 189733b. This is the first time hydrogen sulfide has been detected outside our solar system.
The discovery of hydrogen sulfide and other compounds in the atmosphere of HD 189733b enhances our understanding of planetary science. The higher metallicities found support the understanding that less-massive giant icy planets like Neptune and Uranus accumulated more ice, rock, and other heavy elements relative to gases during early formation periods.
