Photo of a Nuclear Explosion Less than 1 Millisecond After Detonation
This might look like some kind of microscopic organism, but it’s actually a high-speed photograph of a nuclear explosion. It was captured less than 1 millisecond after the detonation using a rapatronic camera. the photograph was shot from roughly 7 miles away during the Tumbler-Snapper tests in Nevada (1952)
This photo of the fireball of the Greenhouse "George" shot was taken 30 milliseconds after the detonation. This test device was among the United States' first thermonuclear experiments. The yield was 225 kilotons (kt), a record held until the Ivy Mike test on November 1, 1952.
