Uncovering Clues to Solar System Formation in Hiroshima's Nuclear Fallout
Scientists have analyzed fallout debris from the 1945 atomic bomb blast in Hiroshima and discovered glassy spheres formed by condensation within the nuclear fireball. The chemical and isotopic composition of these "Hiroshima glasses" bears similarities to primitive meteorites, suggesting they may provide insights into the early Solar System's formation. The study's simulations revealed how different types of glass condensed from the blast's extreme heat, offering a potential window into the chemical reactions during condensation in the early Solar System.
