A Star's Life (Stellar Evolution)

The early stage in the birth of a star when the large body of gas reaches a temperature hot enough for it’s surface to radiate red light, but not hot enough to engage in nuclear fusion.

What will happen to our Sun as it dies?

• It will use up its hydrogen fuel and collapse into a blue dwarf

• As it uses up its hydrogen fuel, it will expand into a red giant before collapsing into a white dwarf

• It will explode in a supernova and collapse into a neutron star

• It will explode in a supernova and collapse into a black hole

• As it uses up its hydrogen fuel, it will shrink into a white dwarf before expanding into a red giant
