就像银河系《Just So Story》中的插图一样，象鼻星云蜿蜒穿过发射区和年轻星团复杂的IC 1396，位于遥远的仙王座。左边是宇宙象鼻，也被称为vdB 142，长度超过20光年。这张详细的望远镜图像显示了明亮的后掠脊和大量凉爽的星际尘埃和气体。但这些黑暗的卷须状星云包含着恒星形成的原料，并将原恒星隐藏在其中。距离我们近3000光年，相对暗淡的IC 1396复合体覆盖了天空中一大片区域，跨度超过5度。这幅作品的视场宽度为1度，大约是两个满月的角度大小。当然，下面和右边伸出的象鼻子的黑色形状，被一些人称为商队。

Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Seen on the left the cosmic elephant's trunk, also known as vdB 142, is over 20 light-years long. This detailed telescopic view features the bright swept-back ridges and pockets of cool interstellar dust and gas that abound in the region. But the dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees. This rendition spans a 1 degree wide field of view though, about the angular size of 2 full moons. Of course the dark shapes below and to the right of the outstretched Elephant's Trunk, are known to some as The Caravan.
