Weather on HD 189733b

Verification: This is a popular metaphor, not a direct observation of rain. HD 189733b is a hot gas giant with temperatures around 1,000°C and extremely strong winds. Its blue color and spectra are consistent with clouds containing silicate particles; NASA describes possible glass-like particle rain driven sideways by the winds. The data do not establish that liquid glass continuously falls over the whole planet.

Conclusion: Atmospheric models suggest silicate clouds and possible “glass” precipitation that powerful winds could carry horizontally. Rain has not been directly observed, and “constantly” is unsupported.
