Question

Explain the life cycle of a star using the terms white dwarf main sequence red giant supergiant supernova nebula and black hole

Very very short paragraph

Answer 1

The life cycle of a star begins with a nebula, where gas and dust coalesce to form a protostar. Once nuclear fusion ignites, the star enters the main sequence phase, where it spends most of its life. As it exhausts its hydrogen fuel, it expands into a red giant (or supergiant for massive stars). Eventually, a red giant sheds its outer layers, leaving behind a white dwarf, while a supergiant undergoes a supernova explosion. The remnants of the supernova may form a neutron star or a black hole, completing the stellar life cycle.
