Unlike a supernova, which destroys the star, a nova ejects only the outermost layer of accumulated material, causing a sudden, dramatic brightening that can make the star visible from Earth with the naked eye. A Type Ia supernova, for example, results from the complete thermonuclear disruption of a white dwarf, often in a binary system where it exceeds the Chandrasekhar limit.

In contrast, a nova involves a partial explosion that leaves the white dwarf intact, allowing the cycle to potentially repeat. Over time, the layers of hydrogen become dense and hot enough to overcome the star’s immense gravity, triggering a runaway nuclear fusion reaction.
Studying these repeated events is crucial for understanding the life cycles of stars, as they offer a glimpse into the repetitive nature of stellar violence long before a potential final supernova explosion. Novae serve as natural laboratories for studying extreme physics, particularly the conditions that lead to thermonuclear fusion.

This sudden flare of light is the direct visual result of the thermonuclear explosion on the white dwarf’s surface. This sudden flare of light is the direct visual result of the thermonuclear explosion on the white dwarf’s surface.
