The outer layers begin to expand, cool and shine less brightly. The expanding star is now called a Red Giant. The star expands to a Red Giant, below. Stage 8 - The helium core runs out, and the outer layers drift of away from the core as a gaseous shell, this gas that surrounds the core is called a Planetary Nebula.A Planetary Nebula.

A nebula is a bunch of atoms and molecules floating in outer space, like a cloud of dust. More than one nebula are called nebulae, because-ae is the plural ending in Latin, just as-s is the plural ending in English.Nebula is the Latin word for a cloud.ventually, inside some nebulae, the dust thickened in some places enough to form new stars, or to form planets around those stars. New nebulae are still forming today, whenever a star explodes into a supernova. One example is the Crab Nebula, which formed in 1054 AD.
