AI Summary

Scientists note that increasing human-made radio noise and ionospheric blockage make detecting low‑frequency extraterrestrial signals, such as the 1977 “Wow!” burst, increasingly difficult from Earth. To overcome these limitations, researchers are racing to construct a radio telescope on the Moon, where the far side offers a quieter environment free from terrestrial interference and ionospheric effects. The proposed lunar instrument would enable clearer monitoring of faint cosmic radio emissions that are now masked by satellite and radar transmissions.
