The first thermal map of any exoplanet depicts the temperatures on HD 189733b, with hotter temperatures appearing brighter. The planet is tidally locked, meaning the same side always faces its star, with the central longitude here directly facing its sun. The map shows that the hottest point is not the middle of the day side, but a spot to the east.
