Explanation: That bright beacon you’ve seen rising in the east just after sunset is Jupiter. Climbing high in midnight skies, our Solar System’s ruling gas giant was at its 2023 opposition, opposite the Sun in planet Earth’s sky, on November 2. But only a few days earlier, on October 28, the Moon was at its own opposition. Then both Full Moon and Jupiter could share this telephoto field of view. The celestial scene is composed from two exposures, one long and one short, blended to record bright planet and even brighter Moon during that evening’s partial lunar eclipse. Moonlight shining through the thin, high clouds over northern Italy creates the colorful iridescence and lunar corona. Look closely and you’ll also spot some of Jupiter’s Galilean moons.

说明: 这阵子紧接在日落后，即从东方升起的那颗明亮天体是木星。11月2日，这颗太阳系最大的气态巨行星，于子夜时高悬在夜空中，处在地球天空与太阳180度反向的2023年冲之位置。而在数天前的10月28日，月球本身也在冲点上。于是这片长焦镜头视野，就记录了同时满相的月亮和木星。这幅天体影像则是由一长及一短的两次曝光所组成，以呈现明亮的行星及当晚发生月偏食、更明亮的满月。拍照的当时，月光穿过意大利北部天空薄薄的高层云，造就了色彩缤纷的彩云和月华景观。如再仔细检视，还可见到木星的部分伽利略卫星。
