what is ufo

A UFO, or unidentified flying object, is any perceived aerial phenomenon that cannot be immediately identified or explained. Most UFO sightings are identified as known objects or atmospheric phenomena, while a small number remain unexplained. Unusual sightings have been reported in the sky throughout history, but UFOs became culturally prominent after World War II, escalating during the Space Age. Some interpret the sighting of UFOs as evidence that extraterrestrial life exists and has visited Earth. The U.S. government currently has two entities dedicated to UFO data collection and analysis: NASAs UAP independent study team and the All-domain Anomaly Resolution Office. Recently, the term UAP (unidentified aerial phenomena) has been used instead of UFO.
