Estrellas y galaxias: los ciclos de vida de las estrellas

Stars undergo a life cycle starting from a nebula, where dust and gas coalesce under gravity to form a protostar. Depending on their mass, stars can live for billions of years, eventually expanding into giants or supergiants. As they exhaust their fuel, stars may become white dwarfs, neutron stars, or black holes. Black holes have intense gravitational forces that prevent even light from escaping.
