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.
🌋 Bring your questions—we’ll be taking them live!

Scientists are getting closer in their search for life beyond earth. But with limited federal funding for the search for extraterrestrial intelligence, supporters are the reason cutting-edge scientists can keep their eyes on the sky.
