Which is the earliest stage of star formation?
Protostar is the earliest stage. This is when the light and heat given off is caused by the friction of the gases passing each other and not by nuclear fusion. This part of the stars life usually lasts about 150,000 years, then it condenses enough to being Nuclear Fusion and a real star is born. See related question.
What is the life cycle of a star?
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant. 1.
