Explanation:
Spooky shapes
seem to haunt this dusty expanse,
drifting through the night in the royal constellation
Cepheus.
Of course, the shapes are cosmic dust clouds visible
in dimly reflected starlight.
Far from
your own
neighborhood,
they lurk above 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 most of 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.
Inside the nebula are the telltale signs of dense cores
collapsing in the early stages
of star formation.
With the eerie hue of dust reflecting bluish light from hot young stars of
NGC 7023, the Iris Nebula
stands out against the dark just left of center.
In the broad telescopic frame,
these fertile interstellar dust fields stretch
almost seven full moons across the sky.
