¿Qué son las estrellas?

The video explains the life cycle of stars, starting with their formation from dust and gases. Stars are classified into three groups based on age and size: main sequence, giants, and white dwarfs. Main sequence stars, like our sun, are stable and powered by hydrogen fusion. As stars age, they become giants, expanding and cooling as they use helium. Depending on their size, they may become white dwarfs or explode as supernovae, leading to neutron stars or black holes. The elements from supernovae contribute to the formation of new stars and planets.
