Scientists warn Starlink satellites disrupt radio telescope research

Recent findings from the Netherlands Institute for Radio Astronomy (ASTRON) indicate that the latest generation of Starlink satellites is significantly disrupting radio telescope observations. The interference from these satellites, particularly the second generation (V2), is reported to be 32 times stronger than that from the first generation. This disruption is particularly concerning for astronomers studying distant galaxies and exoplanets, as the satellites' radiation is obstructing the detection of crucial electromagnetic signals from these celestial bodies. The large size of the satellites, equipped with 3m flat panels and 8m solar arrays, contributes to their impact on astronomical research. Scientists express alarm over the potential long-term consequences of this interference, which could threaten the future of ground-based astronomy across various wavelengths. They emphasize that the value of astronomical research cannot be underestimated, as it may lead to fundamental discoveries in the future. In addition to radio interference, scientists are also worried about light pollution caused by the satellites, which may affect optical telescopes. Experts argue that without effective mitigation strategies, the ongoing deployment of these satellites poses an existential threat to the field of astronomy. They call on SpaceX, as the leading satellite provider, to implement measures to reduce the pollution caused by their satellites. Proposals for improvement include simple modifications, such as shielding the satellite batteries, which could significantly decrease the emitted radiation. The findings have been published in the scientific journal Astronomy and Astrophysics, highlighting the urgent need for action to protect astronomical research from satellite interference.
