The Life Cycle of a Star
8
Main Sequence Star
Nebula
Red Giant
Neutron Star
White Dwarf
Supernova
Black Hole
Gravity pulls hydrogen gas together to form a
cloud. Nuclear fusion occurs which causes the
star to glow. A main sequence star, which can
live for millions or even billions of years,
forms. A red giant forms when the stars
hydrogen level drops. Iron, which acts as an
energy sponge, forms within the star. A
supernova occurs. If it is a massive star, a
neutron star forms. If it is a super massive
star, a black hole forms.
