ESO study warns 100,000 faint satellites may be the safe limit for orbit

AI summary

A new European Southern Observatory study says proposed satellite constellations totaling more than 1.7 million spacecraft could severely harm astronomy by brightening the night sky and creating more image streaks. It concludes that no more than 100,000 faint satellites, below naked-eye visibility, should orbit Earth to reduce damage to observations of distant galaxies, exoplanets, and near-Earth asteroids.
