History Photographed on Instagram: "This archival film shows the 1961 test of the Tsar Bomba, the most powerful bomb ever detonated.⁠ ⁠ Its 50-58 megaton blast was over 1,570 times stronger than the Hiroshima and Nagasaki bombs combined. ⁠ ⁠ Detonated on October 30, 1961, the blast wave circled the globe three times; the flash was visible from 1,000 km, and its cloud reached over 67 km in height."

Oddly Horrifying on Instagram: "In 1958, the United States carried out an underwater nuclear test near Enewetak Atoll in the Marshall Islands. Known as “Wahoo,” the experiment involved detonating a Mark 7 nuclear bomb roughly 500 feet beneath the ocean’s surface. The explosion sent a towering column of vapor soaring more than half a mile into the sky — a striking display of the immense power of early atomic weapons."
