Why
The planet CoRoT-2 b showed westward planetary winds, contrary to theoretical predictions and observations of other hot Jupiters which have eastward winds.
The Frontline Impact
How this affects you
The discovery that CoRoT-2 b rotates slower than it orbits its star challenges existing one-size-fits-all models for hot Jupiters, indicating more complex atmospheric dynamics and tidal locking assumptions are needed for exoplanet research.
