The Pentagon’s department tasked with investigating unidentified flying objects, officially referred to as unidentified anomalous phenomena (UAP), revealed that over 20 reported sightings in the past year remain unexplained. According to the annual report from the Defense Department’s All-Domain Anomaly Resolution Office (AARO), these incidents warrant further investigation due to their unusual characteristics.
Between May 1, 2023, and June 1, 2023, AARO received 757 reports of UAP sightings, 485 of which were newly reported during this period, with the remainder stemming from 2021 and 2022. Most sightings occurred in the skies, although 49 were observed in space. AARO director Jon Kosloski noted that 21 cases remain unresolved and have been identified as “true anomalies,” requiring additional analysis.
The report emphasized AARO’s collaboration with the intelligence community and scientific partners to better understand and assess these cases, particularly those exhibiting anomalous behaviors or characteristics. AARO also pledged to promptly inform Congress if any evidence of advanced foreign aerospace technologies emerges.
Despite the unusual nature of some sightings, Kosloski confirmed that AARO has not uncovered any verifiable evidence of extraterrestrial life, activities, or technology. The cases reviewed so far show no signs of breakthrough aerospace technologies, and the office resolved 118 sightings, attributing them to causes such as balloons, birds, and drones.
The report also highlighted challenges that have hindered AARO’s ability to resolve more cases, citing the lack of timely and actionable sensor data as a significant constraint. To address this, the office is working with military and technical partners to improve sensor capabilities, streamline information-sharing processes, and enhance UAP reporting systems.
