What Causes the ‘Blue Hour’ and Why Is It Magical?

The Blue Hour happens after the sun goes down, but before it’s completely dark. The sky turns blue because sunlight has to travel through more air than usual, and the blue light is what makes it through. It feels magical because it looks like a calm, quiet moment in nature.

Why It Feels Magical

Sometimes, when you’re outside during the Blue Hour, everything seems peaceful and still, like time has slowed down.
