A new European Southern Observatory (ESO) study has found that current proposals to launch more than 1.7 million satellites into orbit, including extremely bright ones, would have "devastating consequences for astronomy." According to the study, no more than 100,000 faint satellites, below naked-eye visibility, should orbit Earth to safeguard our ability to observe the night sky with modern telescopes.
