说明: 行星会聚有如联珠并非偶然。这是因为所有的行星绕行太阳的轨道,几乎都在黄道面上。如果从黄道面上看出去,如同地球住民经常所为,这些行星看起来都分布在同一平面上。不过,如果数颗最亮的行星几乎都出现在同一方向,形同联珠,那这就是纯属巧合了。而这种巧合就出现在上星期;在上面这幅日将落之前、摄于澳洲维多利亚州摩宁屯半岛的主题影像,就同时记录了6颗行星和地球的卫星─月亮。在这张颀长的影像里,还可见到第二道从顶端斜贯而过的带状结构,那是我们银河系的中央盘面。

Explanation: It is not a coincidence that planets line up.That's because all of the planets orbit the Sun in (nearly) a single sheet called the plane of the ecliptic.When viewed from inside that plane -- as Earth dwellers are likely to do -- the planets all appear confined to a single band.It is a coincidence, though, when several of the brightest planets all appear in nearly the same direction. Such a coincidence was captured last week.Featured above, six planets and Earth's Moon were all imaged together last week,just after sunset, from Mornington Peninsula in Victoria, Australia.A second band is visible across the top of this tall image -- the central band of our Milky Way Galaxy.
