Ufology (pronounced /juːˈfɒlədʒiː/) is a neologism coined to describe the collective efforts of those who study reports and associated evidence of unidentified flying objects (UFOs). While ufology does not represent an academic field of research and is widely described as a pseudoscience, UFOs have been subject to various investigations over the years by governments, independent groups, and scientists. The term derives from UFO, which is pronounced as an acronym, and the suffix -logy, which comes from the Ancient Greek λογία (logiā).
