A new study by ESO warns that launching over 1.7 million satellites into orbit, particularly by companies like SpaceX and Reflect Orbital, could have devastating consequences for astronomy. The study suggests that no more than 100,000 faint satellites should be allowed to orbit Earth to protect astronomical observations. This issue highlights the conflict between satellite deployment and the preservation of the night sky for scientific research.
