Extreme Exoplanets: Molten Worlds Around Red Dwarfs

Data from the James Webb Space Telescope reveals a new class of exoplanets—molten worlds with global magma oceans and toxic, sulfur-rich atmospheres. One example, L 98-59 d, appears to sustain its thick atmosphere through continuous volcanic degassing.

This discovery suggests that planets around red dwarf stars may follow a third evolutionary path, expanding our understanding of how diverse—and extreme—alien worlds can be.
