Death of the Sun

The video explains the life cycle of stars, focusing on the Sun. Stars, like humans, are born, live, and die. The Sun will eventually become a red giant, expanding significantly and potentially engulfing the inner planets. As the Sun ages, its heat will increase, rendering Earth lifeless long before the Sun exhausts its nuclear fuel. Eventually, the Sun will shrink into a white dwarf, leaving behind a cold, dim remnant. The remaining planets will orbit this small, dense object, marking the Sun's transition into a dead star.

What happens to a star like the Sun as it approaches the end of its life?

• It explodes as a supernova.

• It becomes a black hole.

• It remains unchanged.

• It turns into a red giant.

What is a significant consequence of the Sun becoming a red giant?

• The Sun will become a black hole.

• The Earth may become lifeless due to increased heat.

• The Sun will gain more planets.

• The Earth will become a new star.

What will the Sun transform into after it can no longer sustain nuclear reactions?

• A neutron star

• A white dwarf

• A red supergiant

• A black hole

What will happen to the remaining planets after the Sun becomes a white dwarf?

• They will orbit a small, dim star.

• They will collide with each other.

• They will be ejected from the solar system.

• They will form a new solar system.

What is the ultimate fate of the Sun after billions of years?

• It will reignite and become a new star.

• It will become a dead star.

• It will merge with another star.

• It will explode as a supernova.
