The Most Relaxing Facts About Cosmic Dust to Fall Asleep To

Tonight’s Sleepy Facts episode is a calm, no-rush drift through cosmic dust—the tiny grains that float between stars, soften starlight, and quietly help build new worlds.

We’ll zoom out to the Milky Way’s dust lanes, then return to the quiet bedside idea that even in stillness, the universe is always moving—softly and harmlessly. Just one more small fact… and then we drift.
