Stars and Planets over Portugal

Explanation: The mission was to document night-flying birds — but it ended up also documenting a beautiful sky. The featured wide-angle mosaic was taken over the steppe golden fields in Mértola, Portugal in 2020. From such a dark location, an immediately-evident breathtaking glow arched over the night sky: the central band of our Milky Way galaxy. But this sky had much more. Thin clouds crossed the sky like golden ribbons. The planet Mars appeared on the far left, while the planets Saturn and Jupiter were also simultaneously visible — but on the opposite side of the sky, here seen on the far right. Near the top of the image the bright star Vega can be found, while the far-distant and faint Andromeda Galaxy can be seen toward the left, just below Milky Way’s arch. As the current month progresses, several planets are lining up in the pre-dawn sky: Jupiter, Venus, Mars, and Saturn.

说明: 原订的任务是要记录夜间飞行的鸟类，然而最后也记录了美丽的星空。这幅经过拼接的广角主题影像，是在2020年摄于葡萄牙梅尔托拉草原的金色田野。从这个黝黑无光害的地点，立即可见的是夜空中令人屏息的光拱：我们银河系的中央盘面。但是这片天空还有更多美景。横过天空的薄云像金色的丝带；火星出现在左方，而在另一侧的天空（右方）可同时见到土星和木星。在影像的顶部附近可找到明亮的织女星，而在左侧的银河拱下方可见到遥远且暗淡的仙女座星系。随着这个月的时光推移，木星、金星、火星和土星会在黎明前的天空排列成行有如连珠。
