Like an illustration in a galactic Just So Story, the Elephant’s Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Of course, the cosmic elephant’s trunk is over 20 light-years long. This composite was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting image highlights the bright swept-back ridges that outline pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees.

如同一個星際的《怎麼回事故事》，大象的鼻子星雲（Elephant’s Trunk Nebula）蜿蜒穿過發射星雲和年輕恆星團複合體 IC 1396，位於遙遠的天鵝座（Cepheus）星座中。當然，這 cosmic 大象的鼻子長度超過 20 光年。這幅合成圖像是通過窄帶濾鏡錄製，傳遞來自該區域中離子化氫、硫和氧原子的光。最終生成的圖像突顯了明亮的後傾峰脊，勾勒出冷的星際塵埃和氣體的口袋。這些嵌入的黑暗觸鬚狀雲團包含了恆星形成的原材料，並在遮蔽的宇宙塵埃中隱藏著原恆星。IC 1396 複合體距離地球約 3,000 光年，這個相對微弱的 IC 1396 複合體在天球上覆蓋了一個大的區域，跨越超過 5 度。
