Jun 19, 2023 · A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light. Supernovas can briefly outshine entire galaxies and radiate more energy than...
Jun 15, 2024 · supernova, any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level. The term supernova is derived from nova (Latin: “new”), the name for another type of exploding star. Supernovae resemble novae in several respects.
Supernovae add enriching elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation. But only a...
A supernova is a powerful explosion of a massive star at the end of its life cycle. This event releases an enormous amount of energy, temporarily outshining an entire galaxy. It also disperses heavier elements formed during the star's life and the explosion itself into the universe. Created by Sal Khan. Questions.
