Unidentified flying object (commonly abbreviated as UFO or U.F.O.) is the popular term for any apparent aerial phenomenon whose cause cannot be easily or immediately identified by the observer.

The United States Air Force, which coined the term in 1952, initially defined UFOs as those objects that remain unidentified after scrutiny by expert investigators, though today the term UFO is colloquially used to refer to any unidentifiable sighting regardless of whether it has been investigated.

UFO reports increased precipitously after the first widely publicized U.S. sighting, reported by private pilot Kenneth Arnold in June 1947, that gave rise to the popular terms "flying saucer" and "flying disc."

The term UFO is popularly taken as a synonym for alien spacecraft and generally most discussions of UFOs revolve around this presumption.

UFO enthusiasts and devotees have created organizations, religious cults have adopted extraterrestrial themes, and in general the UFO concept has evolved into a prominent mythos in modern culture.

Some investigators now prefer to use the broader term unidentified aerial phenomenon (or UAP), to avoid the confusion and the negative connotations that have become attached to UFO.

Another widely known acronym for UFO in Spanish, Portuguese, French, and Italian is OVNI (Objeto Volador No Identificado, Objeto Voador Não Identificado, Objet volant non identifié or Oggetto Volante Non Identificato).

Studies have established that the majority of UFOs are observations of some real but conventional object—most commonly aircraft, balloons, or astronomical objects such as meteors or bright planets—that have been misidentified by the observer as anomalies, while a small percentage of reported UFOs are hoaxes.

Project Blue Book was one of a series of systematic studies of UFOs conducted by the United States Air Force. Started in 1952, it was the second revival of such a study (the first two of its kind being Projects Sign and Grudge).

A termination order was given for the study in December 1969, and all activity under its auspices ceased in January 1970.

Between 5% to 20% of anomalous sightings can be classified as unidentified in the strictest sense.

The likelihood that all UFO sightings are misidentifications of known phenomena inspired some debate in the scientific community about whether any scientific investigation was warranted given the paucity of available empirical data.

Very little peer-reviewed literature has been published in which scientists have proposed, studied or supported non-prosaic explanations for UFOs.

Nevertheless, UFOs as a cultural phenomenon continues to be the subject of serious academic research and amateur investigators continue to advocate that UFOs represent real and unexplained events, whether or not they are associated with alien encounters.

Unexplained aerial observations have been reported throughout history.

Some were undoubtedly astronomical in nature: comets, bright meteors, one or more of the five planets that can be seen with the naked eye, planetary conjunctions, or atmospheric optical phenomena such as parhelia and lenticular clouds.

An example is Halley's Comet, which was recorded first by Chinese astronomers in 240 B.C. and possibly as early as 467 B.C.

Such sightings throughout history were often treated as supernatural portents, angels, or other religious omens.

Current-day UFO-enthusiasts have noticed similarities between some religious symbols in medieval paintings and UFO reports though the canonical and symbolic character of such images is documented by art historians whose commentary and scholarship is generally ignored by enthusiasts.
