A nova is a specific and dramatic event occurring on the surface of a white dwarf star, which is the dense, collapsed core of a once-normal star. This explosion is what we observe as the sudden brightening of a nova.

To understand this phenomenon, one must first grasp the nature of the star itself before exploring the violent explosion that defines the nova. This fusion reaction releases a tremendous amount of energy in a very short time, causing the accumulated surface layer to explode violently away from the dwarf.
This stable phase can last for millions to billions of years, depending on the star's mass. Observational Evidence and Historical Context The evidence confirming that a nova is a star-related event is overwhelming and multi-wavelength.

This cycle of dormancy and eruption is a key characteristic that confirms the persistent stellar nature of the system. Stars with masses up to about eight times that of our Sun do not end in supernovae but instead shed their outer layers gently, leaving behind a hot, dense core known as a white dwarf.
