ELI5: Explain Like I'm 5

Eosphorus

Eosphorus is like a window that allows light to come in. It's a type of layer of molecules and atoms in the Earth's atmosphere. These molecules and atoms scatter the sunlight and let it show up as different colors in the sky. Without the Eosphorus layer, the sky wouldn't be able to appear as colorful and bright. So, it's like a window that helps to make the sky look beautiful.
