Today is another January Blue kind of day…
Anything is possible when the Sky is this blue!
But, why is the sky so blue?? Why not red or purple or green? Am I the only one who wonders about this? Apparently not. 🙂 NASA scientists share the scientific reason for our brilliant blue sky below:
“It is easy to see that the sky is blue. Have you ever wondered why? A lot of other smart people have, too. And it took a long time to figure it out!
The light from the Sun looks white. But it is really made up of all the colors of the rainbow. Like energy passing through the ocean, light energy travels in waves, too. Some light travels in short, “choppy” waves. Other light travels in long, lazy waves.Blue light waves are shorter than red light waves.
All light travels in a straight line unless something gets in the way to—
reflect it (like a mirror)
bend it (like a prism)
or scatter it (like molecules of the gases in the atmosphere)
Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.”

So, that’s the logical reason. Pretty cool.
I also love this 14th century Persian mystic’s “crazy”, illogical thoughts about our blue sky:
“Even
After
All this time
The Sun never says to the Earth,
“You owe me.”
Look
What happens
With a love like that,
It lights the whole sky.”

Hope you’re having a January Blue sky kind of day too. And if you woke up to face a gray sky – inside or outside – what would it take to shift and choose January Blue instead? Just go for it.

Everything else – it’s just the weather.”
