Radio noise from satellite constellations could interfere with astronomers

Large satellite constellations can unintentionally generate electromagnetic noise, creating an additional source of interference for radio astronomers. Astronomers announced July 5 that they detected radio emissions at relatively low frequencies from dozens of SpaceX Starlink satellites as they passed over a Dutch radio observatory. The emissions, at frequencies between 110 and 188 megahertz, are different from the deliberate transmissions from the satellites used to provide broadband internet access between 10.7 and 12.7 gigahertz.
