A Night Sky Vista from Sardinia

Explanation: How many famous sky objects can you find in this image? The featured dark sky composite combines over 60 exposures spanning over 220 degrees to create a veritable menagerie of night sky wonders. Visible celestial icons include the Belt of Orion, the Orion Nebula, the Andromeda Galaxy, the California Nebula, and bright stars Sirius and Betelgeuse. You can verify that you found these, if you did, by checking an annotated version of the image. A bit harder, though, is finding Polaris and the Big Dipper. Also discernible are several meteors from the Quandrantids meteor shower, red and green airglow, and two friends of the astrophotographer. The picture was captured in January from Sardinia, Italy. You can see sky wonders in your own night sky tonight — including more meteors than usual — because tonight is near peak of the yearly Orionids meteor shower.

说明: 在这张影像里，你能认出多少著名的天体呢？这张组合60张涵盖220度天空照片的主题暗空影像，是名副其实的星空珍宝大观园。其中，轻易可见的标志性天体，有猎户腰带、猎户大星云、仙女大星系、加州星云、和亮星天狼及参宿四。如果你需要确认你所见，可以参考上面这幅影像的加注版。稍难辨认的，则有北极星和北斗七星。除此之外，还可见到数颗来自象限仪流星雨的流星、红和绿气辉、与2位天文摄影者的友人。这幅影像是在今年1月，摄于义大利的萨丁尼亚岛。今晚你可亲眼观赏夜空的珍宝，其中包括数量众多的流星，因为狮子座流雨的极大期就在今晚。 （Sardinia 萨丁尼亚岛、撤丁岛）
