50 years ago, satellites threatened astronomers’ view of the cosmos

Satellite interference significantly impacts radio astronomy. U.S. satellites launched in 1974 began causing issues for astronomers observing celestial objects. While few satellites were manageable, the situation has worsened dramatically by 2023, with over 10,000 active satellites now in orbit. These satellites disrupt both radio and optical astronomy, leaving bright streaks in images and emitting excessive radiation.
