Cosmic events are significant occurrences in space that can affect celestial bodies and the universe. Examples include supernovae, which are powerful explosions marking the death of a star, and solar eclipses, where the Moon passes between the Earth and the Sun, temporarily blocking sunlight. These events can provide valuable insights into the workings of the universe. Other cosmic events include meteor showers, which happen when Earth passes through debris left by comets, and black hole mergers, where two black holes collide and release immense energy. Studying these phenomena helps scientists understand the life cycles of stars and the structure of the universe.
