For thousands of years, the night sky has inspired humanity, guided explorers and helped scientists unlock the mysteries of the Universe. As the number of satellites in orbit grows, their reflected light and radio frequency interference become a challenge for both professional astronomy and simple stargazing.
The European Space Agency (ESA) and the International Astronomical Union’s Centre for the Protection of the Dark and Quiet Sky (IAU CPS) have signed an agreement at the International Astronautical Congress to strengthen cooperation and develop technical solutions to keep the sky dark and quiet.
