The video explores the lifecycle of stars, from their formation in cosmic dust clouds to their eventual death. Stars are born through gravitational collapse, shine for billions of years, and die in various ways depending on their mass. Low-mass stars become white dwarfs, while massive stars may explode as supernovae, leaving behind neutron stars or black holes. The remnants of these stars contribute to the formation of new stars and planets, highlighting the cyclical nature of the universe.
