The Soviet Union was on a mission to prove its military might, and on a fateful day in 1961, they succeeded in creating the most powerful explosive device the world had ever seen. Dubbed the Tsar Bomba, this behemoth of a bomb was a hydrogen bomb that packed a whopping 50-megaton punch, leaving a trail of destruction in its wake. The detonation was so massive that it could be seen and felt hundreds of miles away, with a mushroom cloud that pierced the sky like a colossal fist. The scientists who designed it knew they had created something truly remarkable – and truly terrifying.
