Supernovae are extremely powerful and catastrophic explosions of stars that occur at the end of their lifecycle. These events release an immense amount of energy and can briefly outshine entire galaxies before fading away. Supernovae play a crucial role in the formation of heavy elements in the universe and can also trigger the formation of new stars. Studying supernovae can provide valuable insights into the physics of stellar evolution, the structure of galaxies, and the expansion of the universe. Scientists use various observational techniques, such as telescopes and scientific instruments, to study the different types of supernovae and their impact on the surrounding environment.
