Web9 gen 2024 · A supernova is a transient astronomical event that occurs during the last stellar evolutionary stages of a massive star’s life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. The researchers had ruled out the possibility that the observed object is a star pair or comets, halos and terrestrial events.
