Glory (optical Phenomenon)
A glory is an optical phenomenon that resembles an iconic saint's halo about the shadow of the observer's head. The effect is believed to happen due to classical wave tunneling, when light nearby the droplet tunnels through air inside the droplet and, in the case of Glory, is emitted backwards due to resonance effects.
The angular size is much smaller than a rainbow, about 5° to 20°, depending on the size of the droplets. The glory can only be seen when the observer is directly between the sun and cloud of refracting water droplets. Hence, it is commonly observed while airborne, with the glory surrounding the airplane's shadow on clouds (this is often called The Glory of the Pilot). Glories can also be seen from mountains and tall buildings, when there are clouds or fog below the level of the observer. The phenomenon is related to the optical phenomenon anthelion.

Famous quotes containing the word glory:
“So Lycidas sunk low, but mounted high
Through the dear might of him that walk’d the waves,
Where other groves and other streams along
With nectar pure his oozy locks he laves
And hears the unexpressive nuptial song
In the bless’d kingdoms meek of joy and love.
There entertain him all the saints above
In solemn troops and sweet societies,
That sing, and singing in their glory move,
And wipe the tears for ever from his eyes.”
—John Milton (1608–1674)
