What is a Fata Morgana? Cornwall sea mirage sparks questions

A photograph of a rare mirage off Cornwall sparked online speculation about what observers saw, but the scene was a Fata Morgana mirage of an aircraft carrier. The sighting was reported by Mike Hancock of St Ives Boats, who described a surreal, bear-like silhouette on the horizon that many interpreted as a ship or crane. In reality, the phenomenon was a Fata Morgana, a highly complex, fast-changing superior mirage that distorts distant objects into vertically stacked, unrecognizable shapes.

Experts explain that a Fata Morgana results from light bending through layers of air at different temperatures, producing distorted silhouettes that can resemble ships, cranes or other distant objects. The term derives from the Italian for 'Fairy Morgana' and references Morgan le Fay, due to the magical appearance of these illusions. The Cornwall sighting shows how coastal observers can misread natural optics as man-made structures, fueling online speculation before science offers explanations.
