Scott Bray, the deputy director of naval intelligence, shared new details on a database of images and videos that now includes about 400 reports of sightings of unidentified phenomena from 2004 to 2021. While officials were able to attribute some of the sightings to artifacts of certain sensors or other mundane explanations, there were others the officials “can’t explain,” Bray said.
Bray stressed that nothing in the database or studied by a task force set up to investigate the sightings “would suggest it’s anything nonterrestrial in origin.”Both Bray and Ronald Moultrie, the undersecretary of defense for intelligence and security, identified “insufficient data” as a barrier to understanding what the unidentified phenomena are. “That’s one of the challenges we have,” Moultrie said.
That’s something that other scientists can help with, say astrobiologists Jacob Haqq Misra and Ravi Kopparapu.
Science News spoke with Haqq Misra, of Blue Marble Space Institute of Science in Seattle, and Kopparapu, of NASA’s Goddard Space Flight Center in Greenbelt, Md., to learn more about how and why. Their answers have been edited for brevity and clarity, Unidentified aerial phenomena, or UAP, is the term that the military has been using. It’s a little different from the term UFO in the sense that a phenomenon could be something that’s not necessarily a physical solid object. So UAP is maybe a more all-encompassing termterm,
As we consider, Ultimately, I realized for a scientist who wants to understand what’s going on with this UFO thing, there’s a lot of noise to sift through. There’s a lot of public discourse about other topics like crop circles, alien abductions and paranormal stories that muddy the waters, and the more we can be clear about the specific aerial anomalies that we’re talking about, the more we can actually solve the problem.
The researchers’ opinions are their own and do not necessarily represent that of their employers, Since 1968 the number of UFO sightings has dropped off, along with public interest in them.… [The] scientific debunking of the UFO phenomena and the subsequent, though not necessarily connected, decline in sightings presents an interesting behavioral pattern…. UFO reports usually run in five-year cycles and 1972 should be the start of another cycle,
Sightings of unidentified aerial phenomena increased, and in 1948 the U.S. Air Force began an investigation of these reports called Project Sign. The initial opinion of those involved with the project was that the UFOs were most likely sophisticated Soviet aircraft, although some researchers suggested that they might be spacecraft from other worlds, the so-called extraterrestrial hypothesis (ETH). Within a year, Project Sign was succeeded by Project Grudge, which in 1952 was itself replaced by the longest-lived of the official inquiries into UFOs, Project Blue Book, headquartered at Wright-Patterson Air Force Base in Dayton, Ohio. From 1952 to 1969 Project Blue Book compiled reports of more than 12,000 sightings or events, each of which was ultimately classified as (1) “identified” with a known astronomical, atmospheric, or artificial (human-caused) phenomenon or (2) “unidentified.” The latter category, approximately 6 percent of the total, included cases for which there was insufficient information to make an identification with a known phenomenon.
An American obsession with the UFO phenomenon was under way. In the hot summer of 1952 a provocative series of radar and visual sightings occurred near National Airport in Washington, D.C. Although these events were attributed to temperature inversions in the air over the city, not everyone was convinced by this explanation. Meanwhile, the number of UFO reports had climbed to a record high. This led the Central Intelligence Agency to prompt the U.S. government to establish an expert panel of scientists to investigate the phenomena. The panel was headed by H.P. Robertson, a physicist at the California Institute of Technology in Pasadena, California, and included other physicists, an astronomer, and a rocket engineer. The Robertson Panel met for three days in 1953 and interviewed military officers and the head of Project Blue Book. They also reviewed films and photographs of UFOs. Their conclusions were that (1) 90 percent of the sightings could be easily attributed to astronomical and meteorologic phenomena (e.g., bright planets and stars, meteors, auroras, ion clouds) or to such earthly objects as aircraft, balloons, birds, and searchlights, (2) there was no obvious security threat, and (3) there was no evidence to support the ETH. Parts of the panel’s report were kept classified until 1979, and this long period of secrecy helped fuel suspicions of a government cover-up.
A second committee was set up in 1966 at the request of the Air Force to review the most interesting material gathered by Project Blue Book. Two years later this committee, which made a detailed study of 59 UFO sightings, released its results as Scientific Study of Unidentified Flying Objects—also known as the Condon Report, named for Edward U. Condon, the physicist who headed the investigation. The Condon Report was reviewed by a special committee of the National Academy of Sciences. A total of 37 scientists wrote chapters or parts of chapters for the report, which covered investigations of the 59 UFO sightings in detail. Like the Robertson Panel, the committee concluded that there was no evidence of anything other than commonplace phenomena in the reports and that UFOs did not warrant further investigation. This, together with a decline in sighting activity, led to the dismantling of Project Blue Book in 1969,we are urge to find a new way to lead the world.
