Astronomers use phase curves—measurements of how exoplanet brightness changes as they orbit their stars—to infer atmospheric conditions like winds, cloud decks, and heat redistribution without direct observation, revealing dramatic day-night temperature swings and challenging existing planetary formation models.

Maps of Alien Weather: Reading Exoplanet Climates from EarthAdded:
In this episode, researchers unlock alien weather by reading phase curves of exoplanets, revealing winds and dramatic day-night temperature swings.
Using JWST data and other telescopes, teams map atmospheres to show cloud decks, jet streams, and heat redistribution.
Astronomer Dr. Lena Chen explains phase curves let us infer winds without landing, while theorist Raj Kapoor notes these patterns challenge existing models.
Recent observations highlight a cloud-shrouded super-Earth and a lava planet whose weather tests atmospheric stability.
The story underscores curiosity as alien weather becomes a doorway to understanding planet formation.
