Summary
A peer-reviewed study in Scientific Reports (Nature Portfolio, October 2025) analyzed 2,718 days of archival data from the Palomar Observatory Sky Survey (POSS-I, 1949–1957), merging 107,875 algorithmically detected transient objects with 124 above-ground nuclear detonation records and UFOCAT UAP witness reports. The study found transients were 45% more likely within ±1 day of nuclear tests and that each additional UAP report on a given date correlated with an 8.5% increase in transient count. Dates combining both nuclear testing and UAP reports produced the highest transient counts (mean 58.4 vs. 8.55 on baseline days). The authors ruled out photographic plate contamination and speculate that “some transients could potentially be UAP in Earth orbit.” This is the first peer-reviewed study to provide quantitative, instrumental (non-eyewitness) evidence for the nuclear-uap-correlation, directly supporting decades of military witness testimony about UAP clustering near nuclear sites.
Key Claims
- Transients were 45% more likely on dates within ±1 day of a nuclear test. (Bruehl & Villarroel, Spearman correlation)
- Each additional UAP report on a given date corresponded to an 8.5% increase in transient count (negative binomial regression, p = 0.015). (Bruehl & Villarroel)
- Mean transient count on nuclear-test-plus-UAP dates: 58.4 vs. 8.55 on baseline dates. (Bruehl & Villarroel)
- Photographic plate contamination from nuclear fallout was ruled out — fallout produces diffuse fogging, not discrete star-like profiles. (Bruehl & Villarroel)
- “Systematic research of this type has not previously been conducted.” (Bruehl & Villarroel)
- Dataset: 107,875 transient candidates from POSS-I, 124 nuclear detonation records, UFOCAT witness reports over 2,718 days (1949–1957). (Bruehl & Villarroel)
