Reflective Clouds Found Wrapping a Scorched Exoplanet

Observations by the James Webb Space Telescope suggest that the scorching rocky exoplanet TOI-561 b possesses an atmosphere wrapped in reflective silicate mineral clouds. The planet orbits its star every 11 hours with dayside temperatures exceeding 3,000 degrees Fahrenheit. Phase curve measurements revealed that the planet reflects roughly three-quarters of the starlight hitting it and redistributes heat across its surface, pointing to the presence of an atmosphere that scientists hope to further characterize to determine its composition.
