在黎明前逐渐消失的黑暗中，一个倾斜的三角形似乎在西西里岛南端的一个岩层上保持平衡。构成三角形点的是地球天空中可见的四个最亮天体中的三个：木星、金星和月球。虽然月牙很薄，但由于地球的光照，大部分的月盘都是可见的。在2022年4月27日拍摄的这张照片中，金星（中）和木星（左）相距大约3度，并且正朝着近距离会合的方向前进。金星和木星的会合大约每年发生一次，日出前在东方可见，日落后在西方可见。这张特色图片是在地球天空中最亮的物体——太阳到来前大约一小时拍摄的。

In the fading darkness before dawn, a tilted triangle appeared to balance atop a rock formation off the southern tip of Sicily. Making up the points of the triangle are three of the four brightest objects visible in Earth’s sky: Jupiter, Venus and the Moon. Though a thin waning crescent, most of the moon’s disk is visible due to earthshine. Captured in this image on 2022 April 27, Venus (center) and Jupiter (left) are roughly three degrees apart -- and were headed toward a close conjunction. Conjunctions of Venus and Jupiter occur about once a year and are visible either in the east before sunrise or in the west after sunset. The featured image was taken about an hour before the arrival of the brightest object in Earth’s sky – the Sun.
