What is the life cycle of a star from its formation to its death?
Answer 1
Joe Thomas
The life cycle of a star begins with a nebula, a cloud of gas and dust. Gravity pulls the material together to form a protostar. Once nuclear fusion ignites, a main-sequence star forms. Depending on its mass, it may become a red giant or supergiant, then shed its outer layers as a planetary nebula or explode as a supernova. The core remains as a white dwarf, neutron star, or black hole.
