How much energy does a supernova radiate compared to the Sun?
Answer
It radiates as much energy in a few weeks as the Sun produces over its entire ten-billion-year lifespan
The magnitude of energy released during a supernova is staggering. In a very short timeframe—just a few weeks—a supernova emits an amount of radiation equivalent to the total energy the Sun will generate across its entire existence. This massive power output is why these events can briefly outshine entire galaxies and are considered among the most energetic phenomena in the universe.
