The incredible photo above is of the fireball produced by an atomic bomb. Those specs on the ground beneath it are tanks, jeeps and other test vehicles that will be destroyed in a matter of milliseconds. Right below the fireball, a shockwave bouncing off the desert floor and about to merge with the fire is visible.
This stunning shot is just one of many like it in today's New York Times slideshow on photographs of nuclear bomb tests. While these tests were being conducted, it was extremely important for the military scientists involved to see just what was happening, which led to a number of very precisely-timed photos being taken. And man, are they something.
