Life Cycle of a Star

Explain the concept of star formation and the role of nebulae in the birth of stars.

• Nebulae play a crucial role in the birth of stars by providing the necessary materials for star formation and serving as the birthplace of protostars.

• Nebulae are formed as a result of the death of stars, not the birth of new ones.

• Nebulae have no role in star formation and are just random clouds in space.

• Star formation is caused by the collision of asteroids and comets within nebulae.

What are the different stages in the life cycle of a massive star? Describe each stage in detail.

• Nebula, White Dwarf, Black Hole

• Supernova, Red Dwarf, Neutron Star

• The different stages in the life cycle of a massive star are: Nebula, Protostar, Main Sequence, Red Giant, Supernova, and either Neutron Star or Black Hole.

• Protostar, Main Sequence, Red Giant, White Dwarf

What is a supernova and what role does it play in the life cycle of a star?

• A supernova is a powerful explosion that marks the end of a star's life cycle, leading to the formation of a neutron star or black hole.

• A supernova is a process where a star absorbs energy from its surroundings to grow in size.

• A supernova is a stage in a star's life cycle where it cools down and becomes a white dwarf.

• A supernova is a stage in a star's life cycle where it changes its color.
