What is the life cycles of a star?
Stars form from dust and gas known as stellar nebula. Then the
star (depending on its type) will go on to live out its life. In
its dying stage it either turns into a red giant or a red super
giant. Then the star will either go through a planetary nebula or
will go supernova. Afterwards the star will either turn into a
white dwarf, a neutron star, or a black hole.
