When an element formed through the “r” process becomes really heavy (total num-ber of protons and neutrons close to 270), it spontaneously breaks apart through a process called nuclear fission. “The neutrons add very rapidly at a temperature of a few billion degrees, going from iron to uranium in less than 1 second,” Woosley says. rain bournemouth

"WebMoments after the Big Bang, energy begins to condense into matter, protons and neutrons are formed, and then the first element (hydrogen) is formed. Hundreds of millions of years later in stellar nebulae, the hydrogen gas clouds coalesce and, under gravity, form protostars. Nuclear fusion processes begin converting hydrogen into helium.
