"Wet lava ball" exoplanet may have an atmosphere, new evidence shows

TL;DR

NASA researchers have gathered new evidence suggesting exoplanet TOI-561b may have an atmosphere.
TOI-561b is an ultra-hot, low-density super-Earth orbiting its star very closely, completing an orbit in about 11 hours.
James Webb Space Telescope data shows TOI-561b's dayside temperature is about 3,200 degrees Fahrenheit, cooler than the estimated 4,900 degrees Fahrenheit if it lacked an atmosphere.
Scientists propose a thick, volatile-rich atmosphere is needed to explain the observed temperature and other planetary features.
The exoplanet may have bright silicate clouds that reflect starlight, contributing to atmospheric cooling.
Researchers suspect an equilibrium between the planet's atmosphere and its magma ocean, where gases are released and reabsorbed.
Further study of data from the Webb telescope will aim to map TOI-561b's temperature and composition.
