[Interview+] Remember Hycean Worlds? Well, Looks Like They Shouldn't Exist Oct 27, 2025

Show notes

Recently we heard a lot about hyaena planets. They are supposed to be sub-neptunes with thick Hydrogen atmosphere which allows them to maintain a planet-wide liquid ocean in a vast range of conditions. The most famous example of such a planet is K2-18b which was recently observed by JWST. But the latest studies and simulations show that, in fact, hycean worlds are probably much drier and thus the ocean worlds we were envisioning shouldn't exist.
