This discovery contradicts current models because the planet's dayside reaches temperatures of approximately 3,000°C. The presence of methane suggests atmospheric circulation patterns that should not exist at such heat.What's confirmed:The exoplanet WASP-121b has abundant methane on its nightside.Dayside temperatures on WASP-121b reach approximately 3,000°C.Thomas Evans-Soma of the Max Planck Institute for Astronomy led the research team.The team used the James Webb Space Telescope’s Near-Infrared Spect
