Exoplanet Radio takes you on a journey to the farthest and coolest planets in the galaxy. Every day we will share with you some of the most amazing and surprising stories from the world of exoplanet science.

You will find out about the different kinds and features of exoplanets, how they are born and change, how they look and feel, how they could host life and what kind of life that could be, and what they mean for us and our place in the cosmos.

If you are curious about what’s out there, this podcast is for you. You will learn new things, hear fun stories, and get inspired by the wonders and mysteries of exoplanets.

Join us every day for a new episode of Exoplanet Radio, and let’s have some fun exploring the worlds beyond our solar system together.
