Web23 jul. 2024 · The nucleosynthesis that occurs during the explosion of a supernova produces elements with a higher atomic number than iron, which cannot be created by nuclear fusion. When the first stars died out this way, brand new elements, including gold, were formed. Eventually, those elements ended up here on Earth. Web6 jul. 2024 · The oxygen atoms in Earth’s atmosphere were first formed in an old star, along with all the other elements that make up the Earth. When that star exploded (a supernova) all the elements spread out in space. They formed a hot gas cloud where our solar system is today. As the gas cooled, it condensed into rocky and icy planets around …
