The sky appears blue because of Rayleigh scattering. 🌌

When sunlight reaches Earth's atmosphere, it is scattered in all directions by the gases and particles in the air. Blue light travels in shorter, smaller waves, so it is scattered more strongly than other colors, making the sky look blue to our eyes. ☀️💙
