说明: 夜间漂泊在仙王座里的这些幽灵状流形,看来像是在这片美丽星野里肆虐的幽魂。其实,这些奇形怪状的天体,是淡淡反射星光的宇宙尘埃云。这些远在地球外头的星云,位在银河盘面上的仙王座火焰分子云群边缘,离我们大约有1,200光年远。影像中,位在星野右侧,大小超过2光年,比其他幽灵状云气要明亮的vdB 141,亦称为Sh2-136和鬼魂星魂。这团星云内的緻密云核,展现出处在恒星形成阶段的初期、正在发生塌缩的特徵迹象。(Cepheus Flare 仙王座的火焰分子云)

Explanation: Spooky shapes seem to haunt thisjeweled expanse, drifting through the night in the royal constellationCepheus.Of course, the shapes are cosmic dust clouds faintly visiblein dimly reflected starlight.Far from your own neighborhood on planet Earth, they lurk along theplane of the Milky Way at theedge of the Cepheus Flaremolecular cloud complex some 1,200 light-years away.Over 2 light-years across and brighter than the other ghostlyapparitions, vdB 141 or Sh2-136 is also known as theGhostNebula, seen at the right of the starry field of view.Within the nebula are the telltale signs of dense corescollapsingin the earlystages of star formation.
