Why Does It Happen?

Sham S. Misri

Why do we sometime see ring around the moon?

A big ring of light sometime appears around the moon. When this happens there is a thin cloud made of tiny ice crystals floating high in the air. Some of the light rays from the moon pass through or between the ice crystals. When these reach our eyes, we see the moon. But when other rays strike the crystals, a strange thing happens. Instead of going straight on, the rays are bent. When they reach our eyes, they seem to come from a circle that is much bigger than the moon.

This ring is called a ‘HALO’.

Rings appear around the sun, too, and for exactly the same reasons.
