atmosphere, or: why is the sky blue?

For sky friday: a sky memory from a flight that brought a view of the shoreline of Spain.
Here's "continent's end" and the start of waterworld:

And in addition, a sky photo that turned out blurred, but with some photo editing now carries this feeling of flying high above through the atmosphere into the blue:

Which leads to that interersting question again: why exaclty is the sky blue?
Nasa has the answer, here's a short version: "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."
More about it, here:  nasa/sky

It's been three years since I visited Spain, beautiful country and food is spectacular. I used to love flying, but these days, I get worried specially with turbulence.

Beautiful photos!

my great grandson is always asking questions. One is 'why is the sky blue?' It just is... and it's beautiful.
