Story summary
- NASA's James Webb Space Telescope provides clear evidence that the rocky exoplanet TOI-561 b retains an atmosphere.
- TOI-561 b orbits a star twice as old as the Sun, completes a little over a ten-hour orbit, and has a surface temperature near 3,200°F (1,800°C).
- Researchers propose a dynamic equilibrium between the planet's molten interior and its atmosphere, enabling gases to escape and be reabsorbed, challenging existing theories.
