Puffy Giant

WASP-127b, a gas giant 520 light-years away, is larger than Jupiter but far less massive, with unique atmospheric features.

Dynamic Weather

Using ESO's CRIRES+ instrument, researchers revealed complex weather patterns with fast-moving winds and cooler poles.

Chemical Signals

The planet's atmosphere shows water vapor and carbon monoxide, highlighting a multi-layered climate system.

Extreme Heat

Orbiting its star every 4.2 Earth days, WASP-127b experiences intense heat, driving its atmospheric complexities.

Solar Comparison

Neptune's winds reach 1,800 km/h, but WASP-127b’s jet stream dwarfs them, emphasizing its extreme environment.

Tech Power

Ground-based tools like CRIRES+ complement space telescopes like JWST by measuring wind speeds and atmospheric motion.

Future Insights

The upcoming Extremely Large Telescope (ELT) in Chile promises to refine exoplanet studies, uncovering even smaller and more detailed planetary features.
