Astronomers are increasingly concerned about the rapid growth of Elon Musk’s Starlink satellite network, which is generating unintended radiation emissions that complicate the observation of stars and other celestial phenomena.
While light interference from satellite streaks has been a known issue, the radio signals from newer satellites are now causing even greater concern among the scientific community.
Researchers from the Dutch Institute for Radio Astronomy (ASTRON) have revealed that the second-generation Mini Starlink satellites, also known as “V2,” emit interference 32 times stronger than their predecessors.
The Starlink constellation, developed by SpaceX, currently consists of over 6,400 satellites orbiting at an altitude of 550 km, accounting for more than 50% of all satellites orbiting the planet.
These satellites produce radio noise, technically referred to as unintentional electromagnetic radiation (UEMR).
Jessica Dempsey, director of the Dutch institute, told the BBC that this radio interference is “blinding” their telescopes, hindering crucial research into cosmic wonders such as black holes and galaxies.
Dempsey also warned that the situation is gradually worsening, as SpaceX is launching around 40 V2 satellites into orbit every week.
As companies race to provide global broadband coverage, some projections estimate that there could be up to 100,000 satellites in orbit by 2030, dramatically increasing the challenges faced by astronomers. Although issues with the first generation of satellites had already been raised, the new V2 models have exacerbated the problem.
ASTRON is urging international bodies, such as the International Telecommunication Union, to enforce stricter regulations and scrutiny to alleviate the situation.
Last month, SpaceX responded to the concerns, highlighting its efforts to reduce the radio emissions that interfere with astronomical observations through a technique known as “telescope line-of-sight avoidance.”
In a statement, SpaceX reiterated its open invitation to radio astronomy organizations worldwide to adopt this approach and help protect vital scientific research.
This week, Yemen became the first Middle Eastern country to access Starlink’s Internet service, aimed at providing connectivity to remote and underserved communities worldwide.
Yemen, ravaged by a civil war since 2014, is experiencing one of the worst humanitarian crises globally. Starlink’s Internet access will serve as a lifeline for essential services in the affected areas and support the work of international aid agencies.
