đ¨ Starlink satellites are leaking radio waves â flooding space with noise.
And it's threatening our ability to study the universe.
A new study has revealed that second-generation Starlink satellites are emitting unexpected levels of radio wave pollutionâposing a serious threat to astronomy.
Researchers using the LOFAR radio telescope network in Europe detected electromagnetic radiation leaking from 97 Starlink satellites in frequencies crucial for space research, including the 150â153 MHz band specifically reserved for radio astronomy.
These signals are up to 32 times stronger than those from earlier Starlink models, and a single satelliteâs leakage is 10 million times brighter than the faint cosmic signals astronomers are trying to detect.
This invisible interference is becoming more severe as SpaceX continues to launch around 40 new satellites per week, while other companies like Amazon and OneWeb also ramp up their own orbital networks. Unlike the visible streaks satellites leave in telescope images, radio wave pollution cannot be filtered outâit simply overwhelms sensitive instruments. With no international rules regulating this kind of electromagnetic leakage, scientists warn we may be closing a vital window into the universe. Without intervention, we risk losing not only our ability to study black holes, stars, and the early cosmosâbut also the innovations that radio astronomy has historically made possible.
