Increased Satellites Blind Terrestrial Telescopes

A new study warns that the proliferation of satellites in low Earth orbit poses a serious threat to astronomical observations from the ground, with projections suggesting that if satellite numbers reach 100,000, ground-based telescopes will lose their ability to function effectively.

• The research highlights that current satellite constellations operated by companies such as SpaceX's Starlink are already causing significant disruptions to telescope observations.
• According to the study, each additional satellite launched into low Earth orbit reduces the quality of astronomical data collected by ground-based telescopes.
• Scientists warn that without regulatory measures, the cumulative effect of tens of thousands of additional satellites could render many ground-based observatories scientifically obsolete.. While previous reports have focused on the impact of satellite brightness on observations, this study emphasizes the broader systemic threat posed by the sheer volume of satellites and their collective interference with telescope operations across multiple wavelengths of observation.

# If the number of satellites reaches one hundred thousand, ground-based telescopes will become nearly blind
