A supernova is a powerful and luminous stellar explosion. It is the largest explosion that takes place in space and is marked by a sudden brightening of a star. Supernovae are more energetic than novae. They are the source of the heaviest elements in the universe and play a significant role in enriching the interstellar medium with elements. Supernovae can briefly outshine entire galaxies and radiate more energy than our Sun will in its entire lifetime.
