Moonbows: 8 stunning photos of the rare night sky phenomenon
Moonbows are super-cool and super-rare. But what are they? And how can you see one?
Moonbows occur when light is refracted through water droplets, in exactly the same way as a rainbow. However, the main difference is the light source. A moonbow gets its light from sunlight reflecting off the Moon, rather than directly from the Sun.
As they are produced when there is much less light, they are a lot harder to spot with the naked eye, and often appear as just a white ring. This also makes them harder to photograph.
And because there is more light around when the Moon is at its fullest, moonbows are easier to spot during a full Moon phase.
We have pulled together some great images from around the world so you can see this natural wonder for yourselves.
