The central star still looks bright; it's considered that the planetary nebula just starts to release gas, fairly newly nebula formed from a dead star. The gaseous region will spread out increasingly within several ten thousand years, and evolve into a splendid planetary nebula like the Ring Nebula (M57) or Dumb-bell Nebula (M27). |
