Explanation:
Spooky shapes seem to haunt this
jeweled expanse, drifting through the night in the royal constellation
Cepheus.
Of course, the shapes are cosmic dust clouds faintly visible
in dimly reflected starlight.
Far from your own neighborhood on planet Earth, they lurk along the
plane of the Milky Way at the
edge of the Cepheus Flare
molecular cloud complex some 1,200 light-years away.
Over 2 light-years across and brighter than the other ghostly
apparitions, vdB 141 or Sh2-136 is also known as the
Ghost
Nebula, seen at the right of the starry field of view.
Within the nebula are the telltale signs of dense cores
collapsing
in the early
stages of star formation.
