橙色的蓝月
Clouds curling around the full “blue” moon gives the night sky an eerie feel in this image from Aug. 19, 2024. As seen here, a blue moon is not actually blue; the third full moon in a season with four full Moons is called a “blue” moon.
Another moon will be visible in the sky the morning of Oct. 25: Jupiter’s icy moon Europa, the destination of NASA’s recently launched Europa Clipper, will be easily observable with binoculars on one side of Jupiter by itself.

在2024年8月19日拍摄的这张照片中，“蓝色”满月周围云雾缭绕，给夜空带来一种阴森恐怖的感觉。如图所示，蓝月实际上并不是蓝色的；在有四个满月的季节中，第三个满月被称为 “蓝”月。
10月25日早上，天空中还能看到另一颗卫星：木星冰冷的卫星木卫二，NASA最近发射的欧罗巴快船的目的地，将很容易用双筒望远镜在木星一侧单独观测到。
