There's something mysterious in the sky. Sometimes it's a saucer-shaped object. Sometimes it's a series of lights that change in formation, color and speed. Other times someone steps forward to admit that the mystery is, well, nothing more than a hoax. One thing is certain: the phenomena of UFOs, or unidentified flying objects, will keep many with their eyes (and cameras) fixed on the skies for years to come.
