Aligned, Multiple-transient Events in the First Palomar Sky Survey
"Aligned, Multiple-transient Events in the First Palomar Sky Survey" and "Transients in the Palomar Observatory Sky Survey (POSS-I) may be associated with nuclear testing and reports of unidentified anomalous phenomena" are the names of two companion papers published in October 2025 in ''Publications of the Astronomical Society of the Pacific'' and ''Scientific Reports'', respectively. The principal authors of the two papers were astronomer Beatriz Villarroel and clinical psychologist Stephen Bruehl.The authors of the two papers contended that their research indicated the potential presence of UFOs orbiting the Earth in the 1950s. Their conclusions or research methodology were criticized by physicists including Michael Wiescher, Nigel Hambly, Kevin Knuth, and others. Provided by Wikipedia
