Pentagon study finds no sign of alien life in reported UFO sightings going back decades

Pentagon study finds no evidence of aliens in reported UFO sightings, dispelling conspiracy theories and confirming misidentifications.

A U.S. Pentagon study released Friday that examined reported sightings of UFOs over nearly the last century found no evidence of aliens or extraterrestrial intelligence, a conclusion consistent with past U.S. government efforts to assess the accuracy of claims that have captivated public attention for decades.

The study from the Defense Department’s All-domain Anomaly Resolution Office analysed U.S. government investigations since 1945 of reported sightings of unidentified anomalous phenomena, more popularly known as UFOs. It found no evidence that any of them involved signs of alien life, or that the U.S. government and private companies had reverse-engineered extraterrestrial technology and had conspired to hide it from the public.

It dispelled claims, for instance, that a former CIA official had been involved in managing the movement of and experimentation on extraterrestrial technology and said a purported 1961 intelligence community document about the supposed extraterrestrial nature of UFOs was actually inauthentic.

“All investigative efforts, at all levels of classification, concluded that most sightings were ordinary objects and phenomena and the result of misidentification,” said the report, which was mandated by Congress. Another volume of the report will be out later.

U.S. officials have endeavored to find answers to legions of reported UFO sightings over the years, but so far have not identified any actual evidence of extraterrestrial life. A 2021 government report that reviewed 144 sightings of aircraft or other devices apparently flying at mysterious speeds or trajectories found no extraterrestrial links but drew few other conclusions and called for better data collection.

The issue received fresh attention last summer when a retired Air Force intelligence officer testified to Congress that the U.S. was concealing a longstanding program that retrieves and reverse engineers unidentified flying objects. The Pentagon has denied his claims, and said in late 2022 that a new Pentagon office set up to track reports of unidentified flying objects — the same one that released Friday's report — had received “several hundreds” of new reports but had found no evidence so far of alien life.
