What Is Stellar Evolution? | Facts About The Lifecycles of Stars

The video tutorial explores the stages of stellar evolution, starting from the formation of stars in molecular clouds, through the protostar phase, and into the main sequence stage. It explains the role of gravity, molecular hydrogen, and cosmic dust in star formation, and describes the transition from protostars to T Tauri stars and eventually to main sequence stars like the Sun. The tutorial highlights the processes of nuclear fusion and the balance of forces that sustain a star's lifecycle.

Explain the process that leads to the formation of a main sequence star.
