船底座大星云是南部天空的一颗明珠，它更谦虚地称为NGC 3372。它是银河系最大的恒星形成区之一，跨度超过300光年。像更小、更偏北的猎户座大星云一样，船底座星云很容易用肉眼看到。但在7500光年的距离上，它的距离是我们的5倍。这张令人惊叹的望远镜照片揭示了该地区星际气体发光细丝和模糊的宇宙尘埃云的非凡细节。船底座星云是年轻的、巨大的恒星的家园，包括仍然是谜一样的变星船底座埃塔，这颗恒星的质量远远超过太阳的100倍。船底二是这片区域中央黑暗缺口上方的一颗明亮的恒星，位于布满尘埃的锁孔星云（NGC 3324）的左侧。

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).
