About this episode

The episode discusses NASA's discovery of a hidden liquid ocean inside Mimas, challenging previous beliefs about the moon's geological activity.

How did we get Mimas so wrong? We used to think Mimas was a dead world, famous only for the massive crater that gives the moon an uncanny resemblance to the Death Star. But in 2024, scientists discovered a secret hidden beneath its battered shell: a vast, liquid ocean we didn’t know existed. Join us to find out what’s really happening inside Saturn’s most surprising moon.▀▀▀▀▀▀ If you love learning about science as much as I do, head to http://brilliant.org/astrum to learn for free for a full 30 days.
