Life Cycle of a Star - Virtual Reality Animation

The video explores the cosmic environment where stars are born from interstellar clouds. It explains the conditions necessary for star formation, including the role of gravity and angular momentum. The lifecycle of stars is discussed, focusing on nuclear fusion processes and the concept of hydrostatic equilibrium. The video concludes with the impact of supernova explosions, which contribute to the cosmic cycle by creating conditions for new stars to form.
