Supernovae Observations

Supernovae are powerful stellar explosions that mark the end of a star’s life cycle, releasing immense energy and light. Astronomers observe these explosions to study the universe's expansion, understand the behavior of distant galaxies, and measure cosmic distances. By analyzing the brightness and light curves of supernovae, scientists can estimate how far away they are and gain insights into the nature of dark energy and the universe’s growth. These observations are crucial for unraveling the universe's history and the fundamental physics governing cosmic evolution.
