In a new study published in the journal Astronomy & Astrophysics, scientists from the Netherlands Institute for Radio Astronomy have raised concerns about the network of satellitesSpaceX low orbit.
According to the researchers, satellites emit "unintentional electromagnetic radiation", which can have negative impacts on the study of deep space. During a one-hour observation, 47 of the 68 satellites analyzed were detected with this radiation emission.

Such a discovery raises questions about the possible side effects of the satellite network on astronomical research and highlights the importance of monitoring and mitigating possible environmental and scientific impacts caused by the growing constellation space.
The Starlink satellites, chosen because of their abundant amount in the sky compared to other low-orbiting satellites, were observed by the Low-Frequency Array Telescope in the Netherlands.
This telescope is considered the largest in the world operating at the lowest frequencies that can be observed from Earth, according to the Netherlands Institute of Radio Astronomy.
Consisting of 40 radio antennas spread across Europe, the telescopehas the ability to detect wavelengths of radiation coming from the most distant regions of space.
This observation resulted in the detection of unintentional radiation emitted by 47 of the 68 satellites analyzed. This raised concerns about Starlink's potential impact on deep space research and astronomical observation.

Through the telescope, scientists were able to identify the frequencies of the Starlink satellites, located in the range of 110 to 188 megahertz — a unit of measurement used for waves electromagnetic. This frequency spectrum covers a protected band ranging from 150.05 to 153 megahertz, making such a discovery even more relevant.
The existence of this protected band, designated specifically for radio astronomy research in the space, has raised concerns among scientists, due to the possibility of radiation from satellites starlinkaffect observations.
The question of potential interferences in scientific activities in this region of the spectrum worries the astronomers community. So far, there has been no response to the issue raised.
