The simple definition captures the immense release of energy and light that briefly outshines entire galaxies. Type Trigger Progenitor Star Type Ia Thermonuclear explosion of a white dwarf White dwarf in a binary system Core-Collapse Core implosion due to iron accumulation Massive star (8+ solar masses).
Supernova Simple Definition Star Life Cycle
This event occurs when a star depletes its nuclear fuel, leading to a catastrophic collapse or violent disruption. A supernova represents the spectacular explosion of a star, marking one of the most energetic events in the universe.
Iron cannot be fused to release energy. This light allows astronomers to study the chemical composition of the ejecta and the physics of the explosion itself.
