Whats a supernova
1 answer
A supernova is a powerful and luminous stellar explosion that occurs at the endpoint of a massive star's life. It is one of the most violent events in the universe. During a supernova, an enormous amount of energy is released in the form of light, heat, and shock waves. The explosion is so bright that it can outshine an entire galaxy for a brief period of time. Supernovae are important events because they synthesize and distribute heavy elements (such as iron, silicon, and calcium) into space, which are necessary for the formation of new stars and planetary systems.
