UFO stands for "Unidentified Flying Object." It refers to any object or light seen in the sky that cannot be identified as a known or recognizable object or phenomenon.
UFO sightings are often associated with the possibility of extraterrestrial life or advanced technology.
While many sightings can be explained as natural phenomena or man-made objects, there are still some sightings that remain unexplained.
The study of UFOs is known as ufology, and it has been the subject of much controversy and speculation over the years.
