Captured by cameras in the North 10,000 bunker, these frames offer researchers precise data on the behavior of the detonation. The collection, featured in a new book from the University of Chicago Press, documents the technical challenges faced by early nuclear scientists in measuring the intensity of the first atomic explosion.

Forgotten photos of the Trinity detonation show the immensity of the project

At 0.016 seconds after the atomic detonation, the fireball was already hundreds of meters wide. The tiny squares to the left and right in this image are billboards 200 meters from the center of the explosion.

That was the moment when human beings first unleashed the power of the nucleus in an immense, blinding ball of fire above a gloomy stretch of desert in the Jornada del Muerto basin in New Mexico.
