仙王座的象鼻
The Elephant's Trunk in Cepheus

象鼻星雲就像銀河系故事中的一幅插圖,蜿蜒穿過發射區和年輕星團IC 1396 ,位於高而遠的仙王座。這個宇宙大象的軀幹也被稱為 vdB 142 ,長度超過 20 光年。詳細的望遠鏡檢視顯示了該區域明亮的後掠脊和大量的冷卻星際塵埃和氣體。但是,黑暗的卷鬚狀雲層中蘊含著恆星形成的原材料,並隱藏著原恆星。IC 1396 是一個相對暗淡的星團,距離我們將近 3000 光年,在天空中覆蓋了一大片區域,跨度超過 5 度。不過,這個渲染圖的視場寬度為 1 度,大約相當於 2 個滿月的角度大小。
原文: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. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long. The 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.
