In this manner, how many nuclear bombs is a supernova?

Supernovae are one of the most energetic explosions in nature, equivalent to the power in a 10²⁸ megaton bomb (i.e., a few octillion nuclear warheads).

Additionally, how strong is a supernova? Found: The Most Powerful Supernova Ever Seen. Astronomers have glimpsed the most powerful supernova ever seen, a star in a galaxy billions of light-years away that exploded with such force it briefly shone nearly 600 billion times brighter than our Sun and 20 times brighter than all the stars in the Milky Way combined.

Besides, what is supernova explosion?

The brilliant point of light is the explosion of a star that has reached the end of its life, otherwise known as a supernova. Supernovae can briefly outshine entire galaxies and radiate more energy than our sun will in its entire lifetime. They're also the primary source of heavy elements in the universe.

How big is a supernova explosion?

These stars end their evolutions in massive cosmic explosions known as supernovae. When supernovae explode, they jettison matter into space at some 9,000 to 25,000 miles (15,000 to 40,000 kilometers) per second.
