天空中那些条纹是什么？一个星系，许多卫星轨迹，和一些流星。首先，在遥远的地方，我们银河系的壮丽带沿着左边延伸。与之相对应的是几颗绕地球轨道运行的星链卫星的平行轨迹。许多较暗的卫星轨迹也在图像中纵横交错。这两条短而明亮的条纹是流星——很可能是一年一度的埃塔水瓶座流星雨的成员。金星在右下方闪耀。金星和卫星通过反射的阳光发光。这张特色照片是5月4日在阿根廷利梅河上空几个小时内拍摄的照片的合成。

What are all those streaks in the sky? A galaxy, many satellite trails, and a few meteors. First, far in the distance, the majestic band of our Milky Way Galaxy runs down the left. Mirroring it on the right are several parallel trails of Earth-orbiting Starlink satellites. Many fainter satellite trails also crisscross the image. The two short and bright streaks are meteors — likely members of the annual Eta Aquariids meteor shower. The planet Venus shines on the lower right. Venus and the satellites shine by reflected sunlight. The featured picture is a composite of exposures all taken in a few hours on May 4 over the Limay River in Argentina.
