The Life Cycle of Stars and the Impact of Mass

The video explains the life cycle of stars, starting from their formation as nebulae, progressing through the protostar and main sequence stages, and eventually evolving into red giants or supergiants. Depending on their mass, stars may end as white dwarfs, neutron stars, or black holes. The process of nuclear fusion is central to these transformations, producing elements up to iron. Supernovae spread these elements across the universe, contributing to the formation of new stars and nebulae.

Explain the difference in the life cycle of stars similar to the sun and much larger stars.

What are the remnants of a star after a supernova explosion?
