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 large cloud that consists of dust and gas. Their  massive size can be as wide as a trillion miles. A huge release of  gas in the interstellar medium produces t â¦ he nebula. The material  contained in the nebula collapses against itself and stars are  formed.hen a protostar is formed from the gas in a nebula, it is the  result of gravitational attraction. This attraction causes matter  to clump together until enough mass has ac â¦ cumulated that it  collapses in on itself and begins the process of fusion.
