Starlink has ruined astronomy. The night sky is over.

Low-Earth-orbit megaconstellations — Starlink first, others behind — add moving sources. Professional pipelines can mask some trails; they cannot pretend the photons were never there. The IAU and several observatories have been in the room with SpaceX. Later satellites are fainter than the first batch. Amazon’s Kuiper and others will add more, so this is an industry problem that Starlink pioneered, not a unique moral defect.

“Ruined” is the overreach. Optical astronomy continues. Radio astronomy has a separate interference fight. Policy tools exist: brightness limits, darkening, coordination windows. The honest card is: impact is real, mitigation is partial, abstinence by one company would not empty the sky.
