Mercury Chases the Sunset
Explanation: This colorful view of the western sky at sunset features last Wednesday's slender crescent Moon. Of course, when the Moon is in its crescent phase it can never be far from Sun in the sky. Also always close to the Sun in Earth's sky is innermost planet Mercury, seen here below and right of center against the bright orange glow along the horizon. Mercury is usually difficult to glimpse because of the overwhelming sunlight, but increasingly better views of the small planet near sunset will be possible as it wanders farther east of the Sun in the coming days. On January 14th, NASA's MESSENGER spacecraft will have a good view too, as it makes its first Mercury flyby.转自成大 一弯斜月带一星，好图。水星的图片，收藏了。 译文：上周三西方多彩的日落景象中纤细的新月悬挂空中。当然新月永远离太阳不远。通常也在太阳附近的还有最里层的行星水星，它就在画面右下方落日的余辉中。由于太阳的光芒水星通常很难观察到，但今后几天当它向东方远离太阳时对这颗太阳附近的小行星的观测状况会越来越好。一月十四日NASA的信使号飞船第一次飞近水星时也会有很好的观测状况。
初次尝试，大家多多指教 MESSENGER要到了，等得胡子花白.......
