UFO phenomena
Mysterious sky objects
UFO phenomena refers to sightings, encounters, and experiences involving unidentified flying objects—anything observed in the sky that witnesses cannot explain.
The phrase encompasses not just the objects themselves but the broader cultural, scientific, and governmental responses they generate: investigations, conspiracy theories, alleged abductions, and debates about extraterrestrial life.
The congressional hearing examined decades of UFO phenomena reported by military pilots.
