Photographer Captures Stunning, Rare Double Moonbow

We've all seen rainbows, but have you ever witnessed a moonbow? Also known as a lunar rainbow, this optical phenomenon happens when moonlight is refracted through water droplets in the air. They're rarer than rainbows, which makes photographer Aaron Watson‘s image of a double moonbow even more special.

Watson of Skies-Alive Photography captured the incredible image in Colorado around 2 a.m., just one day before August's Supermoon Blue Moon.
