Supernova explosions create and scatter elements heavier than iron across space.
NOT BSTOTAL BS
NOT BS — Verdict: True
Verified by Lenz ·
The Short Version
The evidence shows that supernovae do both produce some elements heavier than iron and disperse them through space. NASA, DOE, and review literature support that role in nucleosynthesis and galactic enrichment. The main caveat is that supernovae are not the only major source of heavy elements, and may not be the dominant source for the very heaviest r-process elements.
Caveats
Do not read the claim as saying supernovae are the primary or exclusive source of all elements heavier than iron.
Neutron-star mergers are now strongly supported as a major, likely dominant, source of the heaviest r-process elements.
Many elements heavier than iron also come from other processes, including the s-process in evolved stars, not only from supernova explosions.
