喜欢日落后看西方天空的人最近已经欣赏到了本月一系列引人注目的明亮行星。从一些地方看到，2月18日水星甚至出现在月球后面，这一事件被称为月球掩星。这两张照片是在傍晚的天空中拍摄的，展示了用望远镜观察到的在年轻的月球后面最里面的行星罕见地消失的前后景象。最上面的画面显示明亮的水星正好在被地球光照的月盘的北部（右）边缘可见。在底部的面板中，明亮的行星出现在月亮阳光照耀的新月之外的黑暗天空中。从俄克拉荷马萨利索以南的地球上可以看到，这次月球对水星的掩星只持续了大约3分钟（视频）。但你今晚仍然可以看到行星游行。3月3日：月全食

Fans of the western sky after sunset have lately enjoyed this month's remarkable array of bright planets. Witnessed from some locations, on February 18 planet Mercury even appeared to slide behind the Moon, an event known as a lunar occultation. These two snapshots, taken in early evening skies show before and after telescopic views of the rare disappearance of innermost planet behind young Moon. The top panel finds bright Mercury just visible at the northern (right) edge of the earthshine-illuminated lunar disk. In the bottom panel the bright planet has emerged in darker skies beyond the Moon's sunlit crescent. As seen south of Sallisaw, Oklahoma, planet Earth, this lunar occultation of Mercury lasted only about 3 minutes (video). But you can still check out a parade of planets tonight.
