Amira Shehata wrote Friday, July 21, 2023 09:00 PM Scientists have revealed that there are some things we are losing as Starlink internet satellites and others like them take over the night sky, which includes studying dark matter, observing distant galaxies and finding signs of extraterrestrial intelligence. According to the “business insider” website, a new research paper indicated that SpaceX’s network of low-orbit satellites emits “unintentional electromagnetic radiation” that might negatively affect the study of deep space, and a group of scientists from the Netherlands Institute for Radio Astronomy said they detected radiation on board 47 out of 68 satellites observed over the course of an hour, according to a study published in the journal Astronomy and Astrophysics. The Starlink satellites, chosen for their abundance in the sky compared to other low-orbit satellites, were observed using the Low Frequency Array Telescope in the Netherlands. The telescope is the world’s largest “made up of 40 radio antennas spread across Europe with the ability to monitor wavelengths of radiation from the farthest reaches of space. Scientists detected frequencies from Starlink satellites from 110 to 188MHz, a unit of measurement used for electromagnetic waves, and noted that this range “includes a protected range between 150.05 and 153MHz.” This protected range, reserved for radio astronomers Specifically for the study of space, scientists worried that radiation might affect their observations.Fahey Beromian, a professor of physics and astronomy at the University of Southern California told Dornsev, internal turbulence from Starlink satellites can be compared to a signal that spoils the music from a radio station.As more low-orbit satellites are sent into space, these unintended emissions can be amplified, making Using radio telescopes is more difficult.
