A supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The explosion marks the ultimate demise of the star and briefly outshines an entire galaxy, radiating as much energy as the Sun is expected to emit over its entire lifespan.

Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.
