Firstly the star starts out a protostar which is a gas and dust cloud in space that can go onto form a star.
Low Mass Stars
Protostars - Main Sequence Star - Red Giant - White dwarf - Black dwarf
Smaller stars about the same size of the star (or smaller) swell out, cool down and turn red
High Mass Stars
Protostar - Main Sequence Star - Red supergiant - supernova - blackhole if sufficent mass
Bigger stars end their life much more dramatically!! Such a star swells out to become a super red giant which then collapses. The matter surrounding the star compresses, then the compression suddenly reverses in a cataclysmic explosion known as a supernova. An event like this can outshine the entire galaxy for weeks.
