On this day 80 years ago, a stark and haunting image captured the radioactive plume rising over Nagasaki, photographed from 9.6 kilometers away on Koyagi-jima, moments after the bomb detonated on 9 August 1945.
The nuclear weapon, known as “Fat Man,” was dropped by a Boeing B-29 bomber, unleashing unprecedented destruction across the city. Just six days later, on 15 August 1945, Japan announced its surrender to the Allied powers, bringing World War II to an end.
A single blast that reshaped the closing chapter of the war—and history itself.
