Quizplus · Accepted Answer

A nova happens when a white dwarf star in a binary system accretes material from its companion star. This material can trigger a thermonuclear explosion on the surface of the white dwarf, but it doesn't destroy the star. Instead, it briefly brightens the star, creating a nova. Novae can happen multiple times as long as the conditions for accretion are met.
