## Resource

It's a question most of us ask as children, yet the answer reveals some of the most fascinating principles of physics. Why does the sky appear blue during the day, turn brilliant shades of red and orange at sunset, and become black at night?In this episode, we unravel the science behind the colors of the sky. Discover how sunlight interacts with Earth's atmosphere, why blue light scatters more than other colors, and how a phenomenon known as Rayleigh scattering paints the world above us. We'll also explore the stunning science behind sunsets, the colors of distant planets' skies, and what our atmosphere can teach us about the universe.Join us for a journey through light, color, and the invisible forces shaping the view above our heads. By the end of this episode, you'll never look at the sky the same way again.
