The Life Cycle of Stars from Birth to Death

The video explores the life cycle of stars, starting with their birth from nebulae as protostars. Average-sized stars evolve into red giants, then white dwarfs, and finally black dwarfs. Massive stars become red supergiants, explode in supernovae, and end as neutron stars or black holes. The video clarifies that both Spiky and Bubbles are correct, as star death depends on mass.

What was the main disagreement between Spiky and Bubbles about the fate of stars?

• Whether stars are made of gas or dust

• Whether stars turn into black dwarfs or black holes

• Whether stars become red giants or supergiants

• Whether stars emit light or not

What is the initial stage of a star's life called?

• Red giant

• White dwarf

• Protostar

• Neutron star

What happens to an average-sized star after it becomes a red giant?

• It turns into a black hole

• It explodes as a supernova

• It forms a planetary nebula

• It becomes a neutron star

What is the final stage of an average-sized star?

• Neutron star

• Black dwarf

• Black hole

• Red supergiant

How does the mass of a star affect its death?

• It changes the star's initial formation process

• It determines the color of the star

• It affects the star's temperature

• It influences whether the star becomes a black dwarf or a black hole

What is a supernova?

• The initial stage of a star's life

• A massive explosion marking the death of a massive star

• A small, dense star

• A type of nebula

What remains after a supernova explosion?

• A red giant

• A neutron star or black hole

• A protostar

• A planetary nebula

Why are black holes black?

• They emit no light

• They are made of dark matter

• They are colder than other stars

• They are surrounded by dust clouds

What is the difference in the life cycle of massive stars compared to average-sized stars?

• Massive stars live longer than average-sized stars

• Massive stars do not emit light

• Massive stars become red supergiants and can end as black holes

• Massive stars do not form nebulae

Who was correct in the debate about the fate of stars, Spiky or Bubbles?

• Both were correct

• Neither was correct

• Only Bubbles

• Only Spiky
