A Fata Morgana is a complex form of superior mirage that occurs over the horizon or water. It is caused by the refraction of light rays passing through air layers of different temperatures. This optical phenomenon can create distorted images of objects, making them appear elongated or stacked, often resembling castles or ships. Fata Morgana is most commonly observed in polar regions or over large bodies of water, such as oceans and lakes. The name originates from the Arthurian sorceress Morgan le Fay, who was believed to create illusions to lure sailors. This mirage can be both beautiful and deceptive, captivating those who witness it.
