Astronomer Dr. Beatriz Villarroel joined the Sol Foundation’s 2025 symposium, in Baveno, Italy, to share details about her recent peer-review research publications that show robust evidence for nonanthropogenic UAP. In a series of papers published in the fall of 2025, she demonstrated that photographs from surveys of the night sky taken between 1949 and 1957, in the pre-satellite era, contain hundreds of thousands of temporary star-like points of light, called “transients,” that do not appear in other images of the sky. By using the Earth’s shadow as a filter, Villarroel and her colleagues demonstrated with exceptionally high statistical confidence that tens of thousands of these “transients” are not optical artifacts or defects. Instead, they are likely brief glint-like reflections of the sun off objects of unknown origin with flat, highly reflective surfaces. These objects must be at least several hundred kilometers, and most likely tens of thousands of kilometers, above Earth. These scientists also discovered a statistically significant association among observations of such “transients,” nuclear tests, and historical UAP reporting.
