Supernova

A supernova (Hebrew: סופרנובה, Arabic: المستعر الأعظم, Spanish: supernova, Russian: сверхновая) is a powerful and luminous stellar explosion that briefly outshines an entire galaxy, radiating as much energy as the Sun or any ordinary star is expected to emit over its entire lifespan. Supernovae are extremely important for several reasons: they are a primary source of heavy elements in the interstellar medium from which planets form, they are responsible for the existence of the heaviest elements, and their luminosity makes them useful for measuring cosmic distances. There are several types of supernovae, which are categorized based on their spectral features and the mechanisms that cause the explosion. The most common types are Type Ia, which occur in binary systems where one star accretes matter from a companion, and Type II, which involve the collapse of a massive star's core. Supernovae play a crucial role in the chemical evolution of the universe and the formation of new stars and planetary systems.
