Question

Quizplus · Accepted Answer

A nova is produced by an explosion on the surface of a white dwarf. The explosion happens when the white dwarf pulls material from its companion star, which builds up until it ignites in a burst of nuclear fusion. This explosion causes the star to temporarily increase in brightness and emit a large amount of energy.
