说明: 你对夜空的了解有多少?好的,那么你能从极深空影像里认出着名的天体吗?不论如何,先来个测验,看看你能否从这幅满布昏暗星云的深空影像里,找出一些着名的标誌性夜空天体。这幅影像里,有昴宿星团巴纳德环马头星云猎户大星云蔷薇星云锥状星云参宿七水母星云猴头星云火焰星星云蝌蚪星云毕宿五Simeis 147(义大利麵星云)、海鸥星云、及加州星云。至于它们的真实位置,可参考这张稍带注释的影像。辨认出它们的工作之所以颇有难度,其原因与乍看非常幽暗的天空时,难以认出熟悉的星座雷同:因为我们的夜空织锦具有极深的隐藏複杂性。这幅摄于美国 亚利桑那州幽暗天空下、由总曝光时间超过800小时的28张照片组合而成主题影像,就显现了部分的这种複杂性

Explanation: 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.
