Where
WASP-121 b ·
Why
This study offers the clearest evidence so far that an exoplanet's sunrise and sunset regions might not share the same temperatures or chemical makeup.
The Frontline Impact
How this affects you
The finding gives researchers an unusually detailed view of how weather and atmospheric circulation work on a tidally locked exoplanet and a better way to build three-dimensional maps of alien atmospheres.
