Starlinks are Easily Detected by Radio Telescopes

Visible and infrared astronomers are concerned about light pollution from satellite megaconstellations, and radio astronomers should be concerned too. A team of astronomers used radio telescopes in Australia to image the sky as Starlink satellites overhead. The tests were done at the future Square Kilometer Array facility in Western Australia, using prototype stations that will become part of the array. According to the team, the satellites were easily detectable, and they could see them performing periodic bursts and steady transmissions. When the full SKA comes online, satellites will be another source of radio interference to contend with.
