你对夜空了解多少？好吧，但是你能在一个非常深的图像中识别出著名的天空物体吗？不管怎样，这里有一个测试：看看你是否能在一张充满通常暗淡的尘埃和气体细丝的深图像中找到一些著名的夜空图标。这张照片包含了昴宿星团、巴纳德环、猎户座星云、毕宿五、参宿四、女巫头星云、仙女座环和加利福尼亚星云。为了找到它们的真实位置，这里有一个注释的图像版本。这项任务可能很困难的原因类似于最初很难在非常黑暗的天空中识别熟悉的星座的原因：我们的夜空织锦具有极其深刻的隐藏复杂性。这张特色的合成照片在西班牙格拉纳达的黑暗天空中曝光了16个小时，揭示了其中的一些复杂性。今晚：月全食

How well do you know the night sky? OK, but how well can you identify famous sky objects in a very deep image? Either way, here is a test: see if you can find some well-known night-sky icons in a deep image filled with filaments of normally faint dust and gas. This image contains the Pleiades star cluster, Barnard's Loop, Orion Nebula, Aldebaran, Betelgeuse, Witch Head Nebula, Eridanus Loop, and the California Nebula. To find their real locations, here is an annotated image version. The reason this task might be difficult is similar to the reason it is initially hard to identify familiar constellations in a very dark sky: the tapestry of our night sky has an extremely deep hidden complexity. The featured composite reveals some of this complexity in a 16 hours of sky exposure in dark skies over Granada, Spain. Tonight: Total Lunar Eclipse
