These are some of the most remarkable pictures I have ever come across. I first saw them about 10 years ago, and I just today stumbled on them again. This is a nuclear fireball captured just milliseconds after detonation. A new technology had to be invented to take these photographs, the Rapatronic Camera. http://en.wikipedia.org/wiki/Rapatronic_camera
Since it is challenging to make a mechanical shutter move fast enough to take an image with an exposure time of a few microseconds, a magneto-optical shutter is used instead. A brief change in a magnetic field is used to alter the polarization of the light coming from the fireball, allowing it to pass through two orthogonal polarization filters.
Disturbingly beautiful.

Thank you for sharing. Great info and images. I was in 7th grade and decided to do a school paper on the Atomic Bomb from WWII. I had read Richard Rhodes books on the subject and was fascinated by it. I made scale models of Fat Man and Little Boy. At the time we were still in the 80's and the heat of the Cold War. I received a good grade by the teach wrote to my parents "maybe we should talk about this topic". Looking back I think my teacher looked at me as though I was doing a topic on Torture in the Dark Ages. :-/
