Learning the colors of sunrise and sunset

Now it’s Claire’s turn to ask a why question………….

“Why does the sun make such pretty colors as sunrise and sunset?” asks Claire.

‘Well, it’s all because of light and the fact that light has colour,” says Misty.  “The light around you is a combination of all the colours in the world.”

Misty decides to do more googling to help Claire understand more about this. 

‘Earth goes dancing through space - Our planet, Earth, moves in space with seven other planets nearby. They all spin in circles on the spot, but also move in much larger circles around the Sun. When the Sun is setting in Australia, this means our side of the planet is turning away from the Sun. During sunrise, we’re turning towards it.

Night time happens when we’re no longer facing the Sun at all. Daytime happens when we have twirled to face the Sun directly — so its sunbeams travel (very fast) directly to us. Although you can’t tell by looking at them, beams of light from the Sun come in different sizes. Scientists measure these sizes using something called “wavelength”. Each different wavelength of light has its own unique colour.

But how does it become the gorgeous colours we see during sunset and sunrise?

‘This happens because of an important blanket of air wrapped around Earth, called the atmosphere.   Earth’s atmosphere is made up of many very tiny objects called molecules. In fact, all things are made of molecules, including you and me.

But each molecule is much, much smaller than a grain of sand. They’re so small you can’t see them without a microscope — you can only see the bigger things they make.

If you were an astronaut onboard the International Space Station, you’d have crossed Earth’s atmosphere to get there.’ (Source)

Claire is fascinated with this information. What an eye opener! She asks Misty to keep reading.
