Sun | Can’t Sleep? Learn About Our Nearest Star

November 9, 2026 · 36 min

Show notes

The Sun is a 4.6-billion-year-old star that quietly keeps nearly everything on Earth in business. This episode explores how the Sun formed, what happens inside its intensely hot core, how nuclear fusion produces its enormous supply of energy, and how that energy eventually reaches Earth. Along the way, you’ll learn about sunspots, solar flares, the Sun’s layered structure, and its rather important role at the center of the Solar System.

It’s steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!
