THE LIFE CYCLE OF A STAR.

This article provides an overview of the life cycle of a star. Stars are formed from clouds of gas and dust, which eventually contract under their own gravity and become protostars. Depending on their mass, protostars can become stars like our Sun, brown dwarfs, or planets. Stars that achieve hydrogen fusion stabilize and enter a main phase, where they slowly transform hydrogen into helium. The duration of this phase varies depending on the star's temperature. Low-mass stars eventually become white dwarfs, while mid-sized stars become red giants and eventually white dwarfs. Larger stars undergo a supernova explosion, releasing elements into space and leaving behind either a neutron star or a black hole. The article also mentions some notable stars and galaxies.
