A new survey by Curtin University analyzed the effect of SpaceX’s Starlink satellite constellation on radio telescope images, confirming astronomers’ long-standing concerns about interference with observations of the universe. The study found that up to 30% of images were affected by Starlink satellite emissions, with more than 112,000 radio emissions detected from 1,806 satellites.
The survey identified that many of these interferences are not intentional and come from onboard electronics. Despite current regulations focusing on intentional transmissions, the researchers believe it is essential to update policies to address this type of unintended emission.
Other satellite networks can also cause “leaks” of unintended transmissions, but Starlink’s extensive constellation makes it a primary concern. The study’s findings were published in the journal Astronomy & Astrophysics and aim to support international efforts to regulate the impact of this technology on radio astronomy research.
The team emphasized that while Starlink is not violating current regulations, discussing policies to address this issue is crucial for protecting astronomical observations.
