An exoplanet resembling Jupiter is "hot," and you might not want to visit it, no matter the cost, even if the opportunity arises. The lethal glass rains and the smell of rotten eggs suggest that you probably wouldn't wish to explore the "hot Jupiter" HD 189733 b. Astronomers discovered, using the James Webb Space Telescope, that this gas giant exoplanet, located just 64.5 light-years from Earth and comparable in size to Jupiter, emits a foul odor similar to rotten eggs.
Not only that, but the "hot Jupiter" is also notorious for its lethal glass rains and extreme temperatures, with winds blowing sideways at about 8,046 kilometers per hour. Hence, this planet, discovered in 2005, appears less hospitable, according to Space.com. The conclusion reached by the James Webb Space Telescope is based on the detection of hydrogen sulfide, a molecule that emits the smell of rotten eggs, in the atmosphere of this exoplanet.
This discovery could inform scientists about how the atmospheres of giant gas planets can be influenced by the presence of sulfur, an important element in planetary formation. The "hot Jupiter" orbits its star at a distance of about 4.8 million kilometers, or roughly 3% of the distance from Earth to the Sun, granting it a hot atmosphere and glassy clouds, thus giving it a deceptively calm, marble-like appearance in blue and white.
