Breakthrough UAP Discovery in Astronomy Data with Dr. Beatriz Villarroel

New evidence for UAP-related data has emerged from high-sigma detections of transients that vanish in Earth’s shadow, raising compelling questions about their origin. In this episode of Event Horizon, John Michael Godier speaks with Dr. Beatriz Villarroel, lead scientist of the VASCO Project, about the search for stars and objects that mysteriously disappear from the night sky. They explore the project’s most intriguing discoveries, including multiple transients of unknown origin, the role of citizen scientists, and the profound implications these anomalies may hold for our understanding of the universe.

Dr. Beatriz Villarroel is an astronomer in Stockholm and the lead scientist of the Vanishing & Appearing Sources during a Century of Observations (VASCO) project. VASCO uses automated methods and citizen science to search for stars that have mysteriously disappeared from archival sky surveys, uncovering anomalous “multiple transients” of unknown origin. Her work has earned international recognition, including the L’Oreal-UNESCO For Women in Science award and a TEDx talk on the search for alien artifacts.
