TOI-561 b: Ultra-Hot Exoplanet Has Impossible Atmosphere
The James Webb Space Telescope just discovered something that shouldn't exist—a thick atmosphere on a hellish magma world orbiting so close to its star it should have been stripped bare billions of years ago. TOI-561 b is an ultra-hot super-Earth that defies our understanding of planetary physics.
Scientists found this lava-covered planet is mysteriously cooler than expected, revealing that volatile gases are somehow insulating its surface despite extreme stellar radiation. We explore the strange equilibrium where molten rock and atmosphere continuously exchange materials to maintain this impossible environment, and what this ancient planetary system—formed when the universe was young—reveals about the unexpected diversity of worlds beyond our solar system.
This discovery is rewriting the rules about where atmospheres can survive.
