Some residents in the Durango, Colo. area got a sky high surprise when a strange ring appeared in the sky over the town sparking a number of wild explanations.

The sky ring was not from an alien spacecraft, the Russians or a secret US military aircraft test. It is simply one of the natural wonders of the atmosphere around earth.

A Sun Halo or 22 degree Halo occurs when sunlight both reflects and refracts off of hexagon shaped ice crystals in clouds high in the atmosphere.

The halo is the ice equivalent of the rainbow produced when the sun reflects and refracts off of water molecules in the sky.

A Halo is a marvel to see, and the science behind it is fascinating, but thinking it may be caused by extra-terrestrials makes for a much better story to tell people.
