text: As core hydrogen burning progresses, a very massive star would slowly expand and become more luminous, becoming a blue hypergiant and eventually an LBV while still fusing hydrogen in the core.
text: Planetary nebulae are formed when stars similar to the size of the Sun use up the hydrogen in their core and instead begin fusing hydrogen in an outer shell surrounding the core.
text: Once a star consumes all of its hydrogen, the nuclear fuel that makes it shine, it expands to a red giant.
text: Instead the star will begin to fuse hydrogen in a shell surrounding the core causing it to expand to hundreds of times its original size and cooling its surface, becoming what is known as a red giant.
text: Most red giant stars are still fusing hydrogen in to helium, albeit not in their cores.
