What essential raw materials, crucial for subsequent star and planet formation, are scattered across the galaxy by the ejected stellar material?
Answer
elements heavier than iron
Supernova remnants function as the universe's primary recycling centers by distributing the products of stellar nucleosynthesis. Massive stars forge elements within their cores over billions of years. During the final explosive event, the star flings this processed material outward, critically including elements heavier than iron, which are created during the rapid collapse and explosion itself. This enrichment process scatters the raw materials necessary for the formation of rocky planets and subsequent generations of stars throughout the galaxy, driving chemical complexity.
