Big Points Answer Uranium is a product of nuclear fusion that began in the sun’s core with the fusion of Hydrogen and Helium nuclei into bigger and bigger elements. Once the element iron began to form the star (which couldn’t burn iron as fuel) became unstable, collapsed internally, and then exploded. The massive explosion (brighter than millions of our suns) provided the energy necessary to create all elements bigger than iron—including uranium! Back to Board
