When the study began, less than one in 200 images taken at that time of day contained a satellite. By September 2021, the number was almost one in five. Przemek Mróz: Zwicky Transient Facility is one of the largest sky surveys. It observes the whole visible sky every two nights to search for objects that change their brightness or move. ZTF also captures images of satellite steaks when the satellites cross the field of view of the telescope. We analyzed archival images taken with the ZTF telescope between November 2019 and September 2021 to search for satellite streaks that were captured in our data.
