The Milky Way, Our Galaxy: Learn about other stars compared to our sun and how they will die

The video tutorial explores the lifecycle of stars, starting with our Sun, which undergoes nuclear fusion to shine. As it ages, it will become a red giant and eventually a white dwarf. More massive stars have a different path, becoming supergiants and ending in supernovae, leaving behind neutron stars or black holes. The video also highlights the role of supernovae in the galaxy, contributing to the formation of new stars and elements.

What is the primary process occurring at the core of the sun?

• Nuclear fission

• Nuclear fusion

• Combustion of gases

• Chemical reactions

What happens to the sun when it becomes a red giant?

• It shrinks to half its size

• It expands and forms planetary nebulae

• It turns into a black hole

• It remains the same size

How does a star with three times the mass of the sun end its life?

• As a white dwarf

• As a neutron star

• As a red giant

• As a black hole

What is the final stage of a supergiant star?

• Red giant

• Main sequence star

• White dwarf

• Neutron star or pulsar

What is the significance of supernovae in the galaxy?

• They only occur in other galaxies

• They have no significant impact

• They destroy all nearby stars

• They create new stars and elements

What is the expected fate of Eta Carinae?

• To become a white dwarf

• To remain a massive star

• To explode as a supernova and form a black hole

• To turn into a neutron star

How do supernovae contribute to the universe?

• By creating black holes only

• By forming new galaxies

• By absorbing all nearby matter

• By dispersing elements and aiding star formation
