Supernova
Appearance
Supernova is a transient astronomical event involving the rapid release of energy following the collapse or explosive disruption of a star. It is associated with the production and dispersal of heavy elements.
Supernovae are discussed in astrophysics, stellar evolution, and nucleosynthesis.
Status
Supernovae are observed across the electromagnetic spectrum and, in some cases, through neutrino detection. Models of their mechanisms, progenitor systems, and remnants continue to be developed.
