Dutch scientists have raised concerns that satellites from Starlink, Elon Musk’s satellite internet company, may be “potentially blinding radio telescopes” with the radio waves they emit. Researchers from the Netherlands Institute for Radio Astronomy (ASTRON) made this claim after conducting two observation sessions using the LOFAR (Low Frequency Array) radio telescope, the largest in the world. According to their findings, the electromagnetic signals from Starlink satellites interfere with the radio signals that telescopes like LOFAR rely on for cosmic observations.
LOFAR is a highly sensitive telescope designed to detect faint radio waves from distant galaxies, stars, and other celestial objects. However, with Starlink’s satellites now numbering in the thousands, their transmissions are creating an increasing amount of “radio noise” that can interfere with such astronomical studies. This interference could lead to inaccurate data or blind certain areas of the sky from being effectively studied by radio astronomers.
The ASTRON researchers pointed out that while Starlink is not the only satellite network, its scale and the frequency range it operates in make it a major contributor to the problem. They stress the need for better regulation of satellite frequencies and coordination with scientific bodies to mitigate the impact on radio astronomy.
Meanwhile, Starlink has rapidly gained popularity, especially in remote regions of Africa. Its ability to provide fast internet to underserved areas has been widely welcomed, contributing to improved connectivity in places where traditional broadband infrastructure is lacking. However, this rise in satellite-based internet services could come at the cost of hindering key astronomical research unless both industries find a way to coexist without interference. This issue highlights the delicate balance between technological advancement and preserving scientific research.
