A US satellite detected a mysterious flash in 1979; the CIA said it was probably a nuclear test, but nearly 50 years later, the mystery remains unsolved

A US satellite observed dual flashes in the South Atlantic back in 1979, leading intelligence officials to speculate a nuclear test with notable certainty. Contrary to this theory, a White House committee suggested a meteoroid strike as a more plausible explanation. Yet, revived inquiries over the years indicated potential nuclear activity close to the Prince Edward Islands, marking the incident as a captivating and unresolved tale in nuclear monitoring history.
