A planetary nebula lying near a boundary on Taurus is NGC1514.
You will be able to find out the nebula to trace about 8 degrees northeast from the Pleiades.
The nebula has a diameter of about 2 arc minutes, high-powered view of telescopes shows you a bright central star and very dimmed nebulosity spread out on the outskirts.
The dimmed gaseous matter exposes in bluish color, the matter is emitting light from ionized oxygen atoms.

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).
