It is becoming increasingly clear that light pollution from satellites is having a major impact on astronomy. In a new study, astronomers have sounded the alarm on the risk of satellites interfering with our ability to observe the night sky. The research, published in the Astrophysical Journal Letters, warns that the number of satellites in orbit is growing rapidly and that their light pollution could soon outshine the stars. The paper argues that, if left unchecked, the artificial lights from satellites will have a significant impact on observations from Earth-based telescopes, making it increasingly difficult to make detailed observations of the universe.
