作為南天的一顆璀璨明珠,大船底座星雲被稱為 NGC 3372 。它是銀河系最大的恆星形成區之一,橫跨 300 多光年。和更小、更靠北的獵戶座大星雲一樣,卡琳娜星雲也很容易被肉眼看到。但在 7500 光年的距離上,它的距離要遠 5 倍。這幅令人驚歎的望遠鏡檢視揭示了該區域發光的星際氣體絲和遮蔽的宇宙塵埃雲的非凡細節。船底座星雲是年輕、質量極大的恆星的家園,其中包括仍然神秘莫測的船底座 Eta 變星,這顆恆星的質量是太陽的 100 多倍。 海山二是這一區域中央暗缺口上方的亮星,位於塵封的鎖孔星雲(NGC 3324 )左側。
原文:A jewel of the southern sky, the Great Carina Nebula is more modestly known as NGC 3372. One of our Galaxy's largest star forming regions, it spans over 300 light-years. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye. But at a distance of 7,500 light-years it lies some 5 times farther away. This stunning telescopic view reveals remarkable details of the region's glowing filaments of interstellar gas and obscuring cosmic dust clouds. The Carina Nebula is home to young, extremely massive stars, including the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun. Eta Carinae is the bright star above the central dark notch in this field and left of the dusty Keyhole Nebula (NGC 3324).
