Mobile communication towers represent a relatively new but growing contributor to the total radio-leakage associated with planet Earth. In new research, astronomers from the University of Mauritius and the University of Manchester investigated the overall power contribution of mobile communication towers to the Earth’s radio leakage budget, as seen from three nearby stellar systems: HD 95735, Barnard’s star, and Alpha Centauri A. They found that...
