国际空间站的夜间灯光轨迹

This image of star trails was compiled from time-lapse photography taken by NASA astronaut Christina Koch from aboard the International Space Station, taken in July 2019. This composite image was made from more than 400 individual photos taken over a span of about 11 minutes as the station traveled from Namibia toward the Red Sea.

The image includes many natural and artificial lights that an astronaut may see during an orbit at night. On the ground, stationary features like cities appear as pale yellow-white dotted streaks; with each dot marking another frame captured. Many of the thinner dotted lines with darker orange hues are fires burning across Angola and the Democratic Republic of the Congo.

这张星迹图是由NASA宇航员克里斯蒂娜·科赫于2019年7月在国际空间站拍摄的延时摄影合成的。这张合成图像是由400多张独立的照片组成的，这些照片是在空间站从纳米比亚前往红海的11分钟内拍摄的。

该图像包括许多自然和人造光，宇航员可能在夜晚的轨道上看到。在地面上，像城市这样的固定特征以淡黄白色的斑点条纹出现，每个点都标记着另一个被捕获的画面。在这些用深橙色的点线组成的较细的点线中，有一圈是燃烧在安哥拉和刚果民主共和国上空的火焰。
