Star trails from the ISS

Photo of star trails by an astronaut onboard the International Space Station (ISS).

This image of star trails was compiled from time-lapse photography taken by NASA astronaut Christina Koch on board the International Space Station (ISS) on July 5, 2019. This composite image was made from more than 400 individual photos taken over a span of about 11 minutes as the ISS traveled from Namibia toward the Red Sea.

Koch wrote on Twitter:

City lights, stars, lightning storms, even satellite flares – A composite of individual photos stacked on top of each other to show all the amazing things we see at night out our window.

What are star trails, and how can I capture them?
