supernovae

SOO-per-no-vee

Definition

The plural form of a supernova, which is a powerful and luminous stellar explosion that occurs during the last evolutionary stages of a massive star.

Etymology

Derived from the Latin 'super' (above or beyond) and 'nova' (new), the term was coined because these events initially appear as 'new' stars in the sky that eventually fade.
