#PPOD: This image shows satellites crossing the night sky above the northern Atacama Desert in Chile over just one hour. It is a stack of a time-lapse video taken on 15 October 2025 about two hours after sunset. A few streaks are caused by planes and can be easily identified by their blinking colored lights, but most trails are due to satellites. Credit: F. Kamphues, ESO/M. Kornmesser
