Lurking some 1,200 light-years away at the edge of the Cepheus Flare molecular cloud complex is a ghostly nebula and somewhat isolated Bok globule known as vdB 141 (van den Bergh 141) or Sh2-136 (Sharpless 136). The ghostly shapes of this nebula are cosmic dust clouds that are faintly illuminated in the dimly reflected starlight. This nebula is over two light-years across and at the core of the dark cloud at the top of the nebula in this image, is likely a binary star system in its early stages of formation.
