Striking New Views of the First Atomic Bomb Test

This article highlights new visual records of the Trinity test, the world's first atomic explosion, which occurred on July 16, 1945, in New Mexico. Based on Emily Seyl’s book "Trinity: An Illustrated History of the World’s First Atomic Test," the piece details the extensive photographic effort undertaken by the Manhattan Project to document the detonation of "the Gadget." Photographer Berlyn Brixner, stationed in the North 10,000 bunker, operated Mitchell movie cameras that captured crucial footage used by Los Alamos scientists for initial measurements of nuclear effects. The text describes the physical mechanics of the implosion-type plutonium bomb and the resulting fireball. Although only 11 out of 52 deployed cameras produced usable images due to the extreme conditions, the strategic arrangement of devices at varied distances and angles allowed for a detailed scientific analysis of the blast's behavior. These restored images provide a vivid historical record of the moment humanity entered the nuclear age, offering intricate details of the energy release and debris formation that were invisible to the naked eye.
