Meteors and Satellite Trails over the Limay River

Explanation: 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.

说明: 天空中的那些光痕到底是什么？星系、许多人造卫星迹线、及数颗流星。首先，在遥远的后方，有斜贯过视野左侧的壮丽银河系中央盘面。视野右边与之对应的，有数条平行、由低地球轨道上的星链卫星曳出的迹线。此外，还有数道其他人造卫星的昏暗迹线也交错在影像上。而那2条明亮的短迹线，可能是来自宝瓶座η流星雨的流星。于天空右下角绽放光芒的，则是金星。金星与人造卫星发出的光，全来自太阳。这幅主题影像，是由5月4日数小时期间摄于阿根廷里麦河（Limay River）的多张照片组合而成。
