Supernova
A supernova is a powerful and extremely bright stellar explosion that occurs at the end of a star's life, briefly outshining an entire galaxy and radiating as much energy as the Sun is expected to emit over its entire lifespan.
TECHNICAL DEFINITION
A supernova is a catastrophic stellar explosion, marking the violent death of a massive star (Type II) or the runaway thermonuclear fusion of a white dwarf in a binary system (Type Ia), dispersing heavy elements into the interstellar medium.
BACKGROUND
Outer space, or simply space, is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins.

USAGE NOTE
Supernovae are vital for the creation and distribution of heavy elements necessary for planet formation and are used as standard candles in cosmology.
