Scientists detect hydrogen sulfide on Jupiter-sized exoplanet

Scientists using the James Webb Space Telescope have discovered hydrogen sulfide, a molecule never before found outside our solar system, on the exoplanet HD 189733b, as reported by the CNN.

This hot Jupiter, known for its extreme weather, including glass-like silicate rain and high-speed winds, is located 64 light-years from Earth. The discovery, published in the journal “Nature”, provides new insights into exoplanetary atmospheres.

HD 189733b is the nearest hot Jupiter that can be studied as it transits its star, leading to temperatures of 1,700 degrees Fahrenheit.

Researchers identified hydrogen sulfide, a key sulfur reservoir, along with water, carbon dioxide, and carbon monoxide in the planet’s atmosphere. This finding enhances understanding of exoplanet composition and formation.

Future research will focus on identifying sulfur signatures on other exoplanets and understanding how these compounds influence planetary formation in relation to their stars.
