Episode 11: The Sun
from The Cosmic Classroom Hosted by Sarah Tyk
What's the brightest star in the sky? The Sun, of course! It's also my favorite. In this episode, we'll take a look at that nuclear fusion reactor in the sky. What powers the Sun? How big is it compared to its cosmic counterparts? What is the solar spectrum? Join me as we go "walking on sunshine!"
