英文原文:Explanation: Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus . Far from your own neighborhood on planet Earth , these ghostly apparition s 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 two light-year s across and brighter than the other spooky chimera s, VdB 141 or Sh2-136 is also known as the Ghost Nebula , seen across the middle of the featured image . Within the reflection nebula are the telltale signs of dense cores collapsing in the early stages of star formation. 说明: 在这片由恒星和尘埃交织的星际场域中,有没有任何形状让你感到惊奇呢?这片璀璨[2]的星空,充满了微弱的星光反射云,漂浮在皇家星座仙王座[3]的夜空中。 远离你在地球[4]上的家园,这些幽灵般的幻影[5]潜伏在银河系的平面上,位于距离约1,200光年[6]的仙王座闪焰[7]分子云复合体的边缘。 横跨超过两光年[8],比其他诡异的奇美拉[9](希腊神话中会喷火的怪物)更为明亮,VdB 141 或 Sh2-136[10]也被称为幽灵星云[11],可见于主题图像[12]的中央。 在反射星云[13]中,可以看到恒星形成早期阶段[14]致密内核坍缩[15]的明显迹象。
