What Is the Sun Actually Made Of? A Slow Journey Into Our Star | Space Documentary for Sleep

Tonight, we take a slow journey toward the one star we know best, and ask a simple question: what is the Sun actually made of? Close your eyes and let the narration carry you. There is nothing to remember and nothing to follow closely. If you drift off somewhere between Newton's prism and the heart of the Sun, that is perfectly fine. The short answer: about three quarters of the Sun's mass is hydrogen and about one quarter is helium, with less than 2% everything else (oxygen, carbon, neon, iron and more). Deep in its core, at about 15 million °C, hydrogen slowly fuses into helium, turning around 4 million tonnes of matter into light every second. In this calm space documentary for sleep: • Newton's prism, and the dark lines Fraunhofer found in sunlight • How Bunsen and Kirchhoff learned to read the elements in light • Helium, discovered in the Sun before it was found on Earth • Cecilia Payne, who showed that the stars are mostly hydrogen • Fusion, the long walk of light, and ghostly neutrinos from the core • Sunspots, the solar wind, and the Parker Solar Probe's pass through the Sun's atmosphere Chapters: 0:00 Chapter 1 — The Sun Behind the World 8:18 Chapter 2 — A Rainbow With Gaps 17:36 Chapter 3 — Fingerprints of Light 26:43 Chapter 4 — A Gas Found in the Sun 36:06 Chapter 5 — Mostly Hydrogen 45:52 Chapter 6 — Not a Fire 55:29 Chapter 7 — The Heart of the Sun 1:04:35 Chapter 8 — The Long Walk of Light 1:13:53 Chapter 9 — Ghosts From the Core 1:23:36 Chapter 10 — Weather on the Sun 1:32:37 Chapter 11 — Touching the Sun 1:41:43 Chapter 12 — The Morning Will Come 🌙 New slow science documentaries for sleep, every day.
