Unlike supernovae, novae can explode more than once, increasing their luminosity bythousands of times.

Question

Quizplus · Accepted Answer

Novae are known for their recurrent explosions, which can happen every few decades or centuries. Each explosion increases the luminosity of the nova by thousands of times, making them much brighter than before. In contrast, supernovae are typically only observed to explode once, although there are some exceptions such as Type Ia supernovae in binary systems. Novae can undergo multiple explosions, each increasing their brightness by thousands of times, whereas supernovae are a one-time explosion that can create a brightness increase by billions of times.
