Moonbows, also known as lunar rainbows, happen when the moonlight passes through water droplets, just like a regular rainbow but at night. They’re rarer to spot since the moonlight isn't as bright as the sun, but when conditions are just right—clear skies, a bright full moon, and some rain or mist—you might catch one! It’s such a cool and almost magical sight, like nature’s secret show after dark. Have you ever seen one?
