Muscat: People living in the capital city of Oman were in a treat on Friday evening when they witnessed a halo around the moon.
Rings around the moon are caused when moonlight passes through thin clouds of ice crystals in the Earth's upper atmosphere.
As moonlight passes through the ice crystals, it is bent in a way similar to light passing through a lens. The shape of the ice crystals causes the moonlight to be focused into a ring.
