Astronomy Picture of the Day-2009-每日天文一图第三季 ...-超级军网

因本人时间关系,很难做到每年一张图不落地都发上来,但我会尽力更新
至于说明的翻译问题,由于中文翻译来自北京天文馆,而北京天文馆又很懒,所以偶尔会只有英文的说明

Comet and Meteor
Credit & Copyright: Babak Tafreshi (TWAN) Explanation: This meteor streaking toward the horizon through the early morning sky of January 4th is from the annual Quadrantid meteor shower. Aligned with the shower's radiant point high in the north (off the top of the view), the meteor trail passes to the right of bright bluish star Beta Scorpii. Remarkably, near the top of the trail is a small spot, the fuzzy greenish glow of a comet. Discovered in July of 2007, Comet Lulin (C/2007 N3), is too faint now to be easily seen by the unaided eye, but will likely brighten to become visible to skygazers by late February. The well-timed skyscape featuring both comet and meteor is particularly appropriate as cometary bodies are known to be the origins of planet Earth's annual meteor showers.
说明：1月3日，一道飞向地平线的流星轨迹划破了凌晨的夜空，它来自一年一度的象限仪座流星雨。流星雨辐射点高高地位于北部（影像顶部外侧），流星轨迹划过了明亮的泛蓝色天蝎座β星右侧。其中最为显著的是接近轨迹顶端的小点，那是一个模糊的泛绿色彗星。彗星Lulin（C/2007N3）发现于2007年7月，现在还很昏暗肉眼不能轻易看到，到2月末可能会变亮，天空观测者们届时有机会看到。而这张拍摄时机恰到好处的天空影像，同时拍摄到了彗星和流星，特别是彗星体正好是地球每年一度的流星雨的来源。<meta http-equiv="refresh" content="0; url=http://sdw.cc">

象限仪座流星雨流量很大``一小时有100吧``

。因为木星和木卫三如此明亮，所以许多木星掩木卫三的事件均可以在地球上，透过小型望远镜直接观看。

那边的图都很大的````````

，把你的鼠标放在影像上面还能发现国际空间站的一些主要部件。

A Lenticular Cloud Over New Zealand
Credit & Copyright: Chris Picking (Starry Night Skies Photography)Explanation: What's happening above those mountains? Several clouds are stacked up into one striking lenticular cloud. Normally, air moves much more horizontally than it does vertically. Sometimes, however, such as when wind comes off of a mountain or a hill, relatively strong vertical oscillations take place as the air stabilizes. The dry air at the top of an oscillation may be quite stratified in moisture content, and hence forms clouds at each layer where the air saturates with moisture. The result can be a lenticular cloud with a strongly layered appearance. The above picture was taken in 2002 looking southwest over the Tarurua Range mountains from North Island, New Zealand.

月球上的国际空间站
影像提供及版权：Eric J. Zbinden
说明：2月2日，一轮上弦月闪烁在地球夜晚的天空中。从美国西海岸加利福尼亚州汉密尔顿山附近位置看去，国际空间站在地平线上划过一道弧线，从月球被阳光照亮面前方通过。国际空间站凌月持续时间才0.49秒。在这张清晰的望远镜影像中，拍摄到了空间站在凌月期间，背景是月球表面平滑的澄海。这一太空前哨站从西北向东南运动（从2点位置运动到8点），其距离地球约389公里/230英里。当然，月球本身距离我们要远1,000倍。在这张显著的影像里，闪亮的空间站还反射了地球反照光的蓝色辉光。

现在正扫过太阳系内围的鹿林彗星，在北半球和南半球都是一颗用双筒或小望远镜就能轻易看见的天体。上面这两幅分别拍摄于1月31日和2月4日的影像，呈现鹿林彗星美丽绿色彗核及彗尾的变化。这些在美国新墨西哥州黝黑夜空下所拍摄的影像，涵盖了大约二度的天区。在这两幅影像中，鹿林彗星皆有向左延伸的反向彗尾，而伸展在彗星轨道上的尘尾几乎是侧对着我们。在彗核的右侧，也可见到一道指离太阳的美丽离子尾。如下幅在2月4日拍摄的影像所示，鹿林彗星的离子尾可能在受到太阳风内磁场的拉扯，而发生很有趣的剥离现象。在2007年，美国航天总署的数颗卫星，也在恩克彗星发现类似的彗尾断裂现象。
