The Tarantula Nebula is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud, about 180 thousand light-years away. The largest, most violent star forming region known in the whole Local Group of galaxies, the cosmic arachnid sprawls across this spectacular composite view constructed with space- and ground-based image data. Within the Tarantula (NGC 2070), intense radiation, stellar winds and supernova shocks from the central young cluster of massive stars, cataloged as R136, energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, at the lower right. The rich field of view spans about 1 degree or 2 full moons, in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the local star forming Orion Nebula, it would take up half the sky.
中文翻譯:
🌌 **塔蘭圖拉星雲 (Tarantula Nebula)** 是一個直徑超過一千光年的巨大恆星形成區域，位於附近的衛星銀河 **大麥哲倫雲 (Large Magellanic Cloud)** 中，距離我們約 180,000 光年。它是整個本地星系群中最大、最劇烈的恆星形成區域，這個宇宙中的“蜘蛛”展現了由太空及地面觀測數據製作的壯觀合成圖像。
在塔蘭圖拉 (NGC 2070) 中，來自中央年輕巨星團 **R136** 的強烈輻射、恆星風及超新星衝擊波激發了星雲的光輝，並塑造了蛛網般的絲狀結構。塔蘭圖拉周圍佈滿了其他恆星形成區、年輕恆星團、絲狀結構以及壓扁的氣泡狀雲團。事實上，畫面下方的右邊就是現代最接近的超新星 **SN 1987A** 的位置。這個富饒的視野擴展約 1 度，相當於兩個滿月的大小，位於南天的 **Dorato** 星座中。
如果塔蘭圖拉星雲靠近一點，譬如像本地的恆星形成區 **獵戶星雲 (Orion Nebula)** 距離只有 1,500 光年，它將占據半片天空。
