Life cycle of a star

Nebula

the first stage in every stars life.

Giant cloud of gas and dust

Protostar

the second stage in every stars life, gravity pulls gases and dust together and nuclear fusion starts

Main sequence star

Hydrogen atoms fuse to form helium. This is called nuclear fusion

Red giant

An average or low mass star that expands and cools once it runs out of hydrogen fuel.

Red super giant

A high mass star, it is very similar to the red giant but it expands faster, burns fuel quicker, and gets bigger than the red giant.

Planetary Nebula

Expanding shell of gases shed by a dying star

White dwarf

low mass star that has leftover center of a planetary nebula

Black dwarf

low mass star dies

Supernova

A high mass stars life, after the red super giant. The star runs out of energy collapses and explodes

Black hole

A high mass star end of life - does not have a surface. Gravity is so strong, it absorbs light

Neutron star

Tiny, very dense - collapsed core of a supernova

Hottest star

Blue main sequence

Coolest star

Red giant

Dimmest star

White dwarf

Brightest star

Red giant

These stars are going through nuclear fusion of Hydrogen
