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微弱星云的深图像中找到一些著名的夜空图标。这张图片包含了昴宿星团、巴纳德环、马头星云、猎户座星云、玫瑰星云、锥状星云、参宿七、水母星云、猴头星云、火星星云、蝌蚪星云、毕宿五、西美斯147、海鸥星云和加利福尼亚星云。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揭示了这种复杂性，它是由28张图片拼接而成的，这些图片是在美国亚利桑那州的黑暗天空中拍摄的，历时800多个小时。

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 faint nebulosity. This image contains the Pleiades star cluster, Barnard's Loop, Horsehead Nebula, Orion Nebula, Rosette Nebula, Cone Nebula, Rigel, Jellyfish Nebula, Monkey Head Nebula, Flaming Star Nebula, Tadpole Nebula, Aldebaran, Simeis 147, Seagull Nebula 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 mosaic of 28 images taken over 800 hours from dark skies over Arizona, USA.
