JWST Reveals a Lopsided Alien World with Blistering Evening Winds

New observations from the James Webb Space Telescope (JWST) have revealed that the exoplanet WASP-17 b is noticeably lopsided, with a massive temperature difference between its day and night sides. The atmosphere on the hotter evening terminator edge expanded to 1.8 times the size of the morning side, providing new insights into the dynamics of this well-studied world.
