How do you study volcanoes on a planet more than 200 light-years away?
Join us for SETI Live as host Moiya McTier talks with planetary scientist Claire Marie Guimond about the extreme lava world K2-141 b—a rocky exoplanet so hot that parts of its surface may be covered in oceans of molten rock.
Using advanced mantle convection models, Claire and her collaborators investigated how heat moves through the planet’s interior and where volcanic hotspots may form—including on the planet’s permanent nightside. Together, we’ll explore what these models reveal about alien geology, how lava worlds compare to Earth, and what volcanism might mean for a planet’s long-term evolution.
We’ll also dive into how scientists can study volcanic activity on distant worlds, what makes lava planets important to planetary science, and what questions remain about one of the galaxy’s most extreme exoplanets.
