Life Cycle of a Star
Nebula
Area where new stars form
Large columns
Clouds of interstellar gas
mostly Hydrogen
Collapsing in on itself because of the force of gravity
Particles move very quickly
Nuclear fusion begins in the core of the stars
Star is now on the
main sequence
#
Forces are balanced
Star begins to run out of fuel in its core
Star gets hotter and expands
Star becomes a
red giant
or
red super giant
(If the star is big enough)

Star is not producing any energy and cools until into blackness
This is called a
black dwarf
Heavier stars cannot support their own mass
Star gets destroyed in a supernova explosion and becomes one of the following:
Neutron Star
Black Hole
