This Stellar Blast Showered the Universe with… Calcium | SciShow News

The video explores the origins of elements in our bodies, focusing on how supernovae contribute to the creation of elements like calcium. A recent discovery of a calcium-rich supernova is discussed, highlighting its rarity and significance. Observations from NASA's Swift Space Telescope reveal unexpected X-ray emissions, suggesting a two-phase star death. The mystery of the exploded star's identity remains unsolved, possibly a white dwarf. The video also covers insights into supernova 1987A, revealing a neutron star through ALMA's data, providing new understanding of young neutron stars.
