  1. Supernova nucleosynthesis - Wikipedia

    Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs …

  2. What Is a Supernova? | NASA Space Place – NASA Science for Kids

    Jan 20, 2026 · At their cores, stars convert simple elements like hydrogen into heavier elements. These heavier elements, such as carbon and nitrogen, are the elements needed for life.

  3. Astr - Chapter 21a & 21b Flashcards | Quizlet

    Which type of heavy atomic nuclei are most common, and why? Even numbered elements, for helium is "giant food" for everything beyond itself.

  4. ESA - Supernovas blast iron into interstellar space

    Feb 24, 2025 · Supernova explosions are a crucial step in the chain of events that generates the iron we find in interstellar space and in the Solar System, including on Earth.

  5. Nucleosynthesis – How Elements Are Made

    Jun 22, 2022 · Supernova nucleosynthesis: A supernova produces many intermediate-mass elements between oxygen and rubidium. Largely, this involves rapid neutron-capture, although rapid proton …

  6. The Elementary Nature of Cassiopeia A - Smithsonian Institution

    Oxygen is the most abundant element in the human body (about 65% by mass), calcium helps form and maintain healthy bones and teeth, and iron is a vital part of red blood cells that carry oxygen through …

  7. The Role of Supernovae in Creating Gold and Other Elements

    Mar 29, 2025 · In the intense environment of a supernova, neutrons are produced in vast quantities. These neutrons collide with atomic nuclei, leading to the formation of elements heavier than iron.

  8. What Elements Are Created By Supernova Explosions ... - YouTube

    We’ll discuss how lighter elements like helium, carbon, and iron are produced inside stars through nuclear fusion, and how elements heavier than iron are created during the supernova itself...

  9. Supernova explosions - Las Cumbres Observatory

    At the critical mass, a thermonuclear runaway reaction fuses most of the material to radioactive nickel in a matter of seconds, which then decays to iron. The remaining material is burned into lighter …

  10. Supernova - Wikipedia

    Theoretical studies indicate that most supernovae are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a white dwarf, or the sudden gravitational collapse of a …
