The ancient Greek poet Homer never used a word for blue in The Odyssey or The Iliad, because blue is one of the last colors that cultures pick out a word for In this episode, I'll tell you not only why the sky is blue, but why it's red at sunset. It turns out, those colors are all part of the same sunbeam. And when you're looking at a blue sky, you could be sharing a special moment with someone thousands of miles away. Next time a kid (or the kid inside you) wants to know why the sky is blue, you'll have science to back you up!
