Explanation: 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.

说明: 在黎明前渐褪的黑暗中，一个倾斜的天体三角看似架在西西里岛南端的石峰上。组成这个天体三角的是地球天空中最明亮的4个天体之3：木星、金星和月亮。虽然残月是一抺纤细的银白，但在地照光的照耀下，月亮大部分的月盘皆历历可辨。于2022年4月27日拍下这幅影像时，金星（中）和木星（左）相距大约3度，并即将发生近合。金星和木星的近合大约每年发生一次，可见诸日出前的东方或日落后的西方天空。这幅主题影像，摄于太阳这颗地球天空中最明亮的天体来临前大约１小时。
