A supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star's life. Supernovae are classified into two main types based on their light curves and spectra: Type I and Type II. Type I supernovae do not show hydrogen in their spectra, while Type II supernovae do. Type Ia supernovae are further categorized based on their light curve shapes, with Type Ia-peculiar being a rare subclass. Supernovae are responsible for dispersing heavy elements into the interstellar medium, contributing to the chemical enrichment of the universe. They are also significant for their role in measuring cosmic distances and understanding the expansion of the universe. The study of supernovae provides valuable insights into stellar evolution, nucleosynthesis, and the dynamics of the cosmos.
