Busko conducted an independent search of archival sky photographs from the 1950s, using a separate analytical method designed specifically to verify Villarroel's earlier discoveries.
His investigation uncovered dozens of transient flashes displaying the same unusual signatures reported by the VASCO team, including extremely short-duration bursts of light.
Busko wrote that the findings 'independently confirm the presence of such transients,' adding further weight to the unusual flashes first reported by Villarroel's team.
Many of the mysterious bright spots in both sets of data predate the launch of the first man-made satellite, Sputnik-1, which entered orbit in October 1957, and cannot be explained away as the result of human activity.
