▾A new study has revealed a worrying fact: Starlink satellites from SpaceX, intended to provide internet, produce disruptive radio emissions that threaten space observations by radio telescopes. Emissions from the second generation of Starlinks are up to 30 times stronger than the previous generation, posing a serious problem for astronomers.
Are our windows into the past of the universe darkening? Radio telescopes, which allow us to look billions of years into the past thanks to their ability to capture weak radio waves, are no longer as effective as before. Recently, something has been disturbing them. Paradoxically, the culprits are not distant galaxies but Starlink satellites, which aim to make life better for us here on Earth.
Starlinks polluting the radio spectrum
A new study using the Dutch LOFAR radio telescope has revealed that Starlink satellites from SpaceX, providing internet connectivity, produce disruptive radio emissions. Although they are not emitted intentionally, they are millions of times stronger than the weak signals from space that LOFAR and similar telescopes study.
While the first generation of Starlinks posed a challenge for astronomers, the second generation, launched since last year, is even more problematic. Emissions from these satellites are up to 30 times stronger.
Is the future of astronomy in danger?
SpaceX plans to launch tens of thousands more Starlinks into orbit. If they fail to reduce the radio emissions, it could have catastrophic consequences for radio astronomy.
For telescopes like LOFAR, it would become virtually impossible to find a place in the sky without interference. Fortunately, SpaceX is collaborating with astronomers on a solution. Engineers from both sides are sharing data and looking for ways to reduce the emissions. Only time will tell if they succeed.
Not just about Starlink
However, the problem is not limited to SpaceX. There are an increasing number of satellites from various companies in orbit, and their numbers will rise sharply in the coming years. It is therefore essential that other entities also join in finding solutions and ensure that our desire for internet connectivity does not interrupt the quest for understanding the universe.

Think of the breathtaking vision of the future from the movie Blade Runner – holographic ads, cyberspace, and ubiquitous networks. Can this fiction become reality? Find out what we can expect from the internet of the future and how the boundaries between reality and the virtual world will blur.
PoE – the possibility of power over a network cable
Network ethernet cables are typically used for data transmission. However, the IEEE 802.3af and 802.3at standards also define the function of power over a network cable. This way, you can power small network devices without the need for an additional power cable. Let's focus on the advantages and disadvantages of PoE (Power over Ethernet) and its specifics.
