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 their lifespan is determined by their mass. Low-mass stars become red giants and eventually white dwarfs, while high-mass stars can explode as supernovae, leaving behind neutron stars or black holes. The remnants of stars contribute to the formation of new stars and planets, highlighting the cyclical nature of the universe.
