Why the Sky Changes Colour Throughout the Day

The sky is one of the most familiar sights in our daily lives, yet it constantly changes colour in ways that often go unnoticed. On a clear afternoon, it appears bright blue. During sunrise and sunset, it transforms into breathtaking shades of orange, pink, red and purple. After dark, it becomes a deep black canvas filled with stars. These changes are not random or simply beautiful natural displays. They are the result of sunlight interacting with Earth's atmosphere in remarkable ways. Understanding why the sky changes colour reveals fascinating insights into light, weather and our planet's unique environment, showing that even ordinary moments above us are shaped by extraordinary science.
