ESO study warns 1.7 million satellites would devastate astronomy, recommends limit of 100,000

Summary

A new European Southern Observatory (ESO) study warns that proposals to launch over 1.7 million satellites into orbit, including extremely bright ones, would have "devastating consequences for astronomy." The study is the first to compute how large and bright satellite constellations would affect astronomical observations by making the night sky brighter. It recommends that no more than 100,000 faint satellites (below naked-eye visibility) should orbit Earth to safeguard modern telescope observations. The research also notes concerns about impacts on health and the environment from these satellite megaconstellations.
