| 释义 | supernova (once / 24122 pages) n Supernova is an astronomical term for a star that explodes like crazy. When a star turns into a supernova, it becomes extremely bright. Supernova sounds like a superhero, but it refers to the super explosion of a star. A nova is also the explosion of a star, but a supernova has more energy. A supernova happens when a star becomes bright, bursts, and its matter is scattered in all directions, with light and radiation shooting out.
