说明: 有时候从大範围的地表看出去,天空看似在微笑。上面这幅拍摄时间精准的影像,呈现了2008年这天世界各地见到的月亮、金星和木星不寻常叠合景观,其中世界各处皆可见到的蛾眉月和近合的木星和金星,合来起来形成了一个微笑。这片俯视美国加州洛杉矶市所见的景像,摄于2008年11月30日太阳西落时分的威尔森峰天文台。其中,位在天空最高也最远的是木星。在木星左下方的,是远较邻近的金星,而透过地球大气层的薄云,金星带着不寻常的泛蓝色泽。在最右缘的地平线上方,则是蛾眉相的月亮。在月华的照耀下,薄云映着不寻常的橙色。在影像的下端,有洛杉矶绵延的丘陵,有些还笼罩在薄薄的雾霾里。在影像的左缘,则可见到洛杉矶的摩天大楼群。在拍了这张照片的数小时之后,月亮逐渐移向近合的行星,然后在短暂遮掩了金星后才远离。在这星期地球的广大区域,金星和木星的另一次近合将出现在日出前的东方的天空中。

Explanation: Sometimes, the sky may seem to smile over much of planet Earth. On this day in 2008, visible the world over, was an unusual superposition of our Moon and the planets Venus and Jupiter. Pictures taken at the right time show a crescent Moon that appears to be a smile when paired with the planetary conjunction of seemingly nearby Jupiter and Venus. Pictured here is the scene as it appeared from Mt. Wilson Observatory overlooking Los Angeles, California, USA after sunset on 2008 November 30. Highest in the sky and farthest in the distance is the planet Jupiter. Significantly closer and visible to Jupiter's lower left is Venus, appearing through Earth's atmospheric clouds as unusually blue. On the far right, above the horizon, is our Moon, in a waxing crescent phase. Thin clouds illuminated by the Moon appear unusually orange. Sprawling across the bottom of the image are the hills of Los Angeles, many covered by a thin haze, while LA skyscrapers are visible on the far left. Hours after the taking of this image,the Moon approached the distant duo, briefly eclipsed Venus, and then moved on. This week, another conjunction of Venus and Jupiter is occurring and is visible to much of planet Earth to the east just before sunrise.
