AI overview
A nova is a sudden, dramatic brightening of a star system caused by a thermonuclear explosion on the surface of a white dwarf that is pulling material from a nearby companion star. Novas matter to astronomers because they help us understand stellar evolution, binary star systems, and the physics of extreme conditions in space.
