WASHINGTON — The Pentagon's latest report on UFOs has revealed hundreds of new reports of unidentified and unexplained aerial phenomena but no indications suggesting an extraterrestrial origin.
The review includes hundreds of cases of misidentified balloons, birds and satellites as well as some that defy easy explanation, such as a near-miss between a commercial airliner and a mysterious object off the coast of New York.
While it isn't likely to settle any debates over the existence of alien life, the report reflects heightened public interest in the topic and the government's efforts to provide some answers. Its publication comes a day after House lawmakers called for greater government transparency during a hearing on unidentified anomalous phenomena, or UAPs — the government's term for UFOs.
Federal efforts to study and identify UAPs have focused on potential threats to national security or air safety and not their science fiction aspects. Officials at the Pentagon office created in 2022 to track UAPs, known as the All-Domain Anomaly Resolution Office, or AARO, have said there's no indication any of the cases they looked into have unearthly origins.
''It is important to underscore that, to date, AARO has discovered no evidence of extraterrestrial beings, activity, or technology,'' the authors of the report wrote.
The Pentagon's review covered 757 cases from around the world that were reported to U.S. authorities from May 1, 2023, to June 1, 2024. The total includes 272 incidents that occurred before that time period but had not been previously reported.
The great majority of the reported incidents occurred in airspace, but 49 occurred at altitudes estimated to be at least 100 kilometers (62 miles), which is considered space. None occurred underwater. Reporting witnesses included commercial and military pilots as well as ground-based observers.
Investigators found explanations for nearly 300 of the incidents. In many cases, the unknown objects were found to be balloons, birds, aircraft, drones or satellites. According to the report, Elon Musk's Starlink satellite system is one increasingly common source as people mistake chains of satellites for UFOs.
