MADRID, 3 May. (EUROPA PRESS) –
Scientists from the Universities of Manchester and Mauritius have used data from multiple sources to simulate radio leaks from mobile towers to determine which extraterrestrial civilizations could detect from various nearby stars, including Barnard’s Star, six light-years from Earth.
The research, published in the journal Monthly Notices of the Royal Astronomical Society, found that only the most technologically advanced civilizations could detect current levels of radio leakage from Earth’s moving tower. However, since most alien civilizations are likely to have more sensitive receiving systems and we are moving towards more powerful broadband systems on Earth, detection of humans by other intelligent beings will become increasingly likely.
Professor Mike Garrett, project team leader and director of the Jodrell Bank Center for Astrophysics at the University of Manchester, said it’s a statement: “I have heard many colleagues suggest that the Earth has become increasingly quiet in recent years, a claim I have always questioned. While it is true that today we have fewer powerful radio and television transmitters, the proliferation of Mobile communication around the world is profound.While each system individually represents relatively low radio powers, the integrated spectrum of billions of these devices is substantial.
“Current estimates suggest that we will have over a hundred thousand satellites in low-Earth orbit and beyond before the end of the decade. Earth is already anomalously bright in the radio part of the spectrum; if the trend continues, pWe could be easily detectable by any advanced civilization with the right technology.”
The models, which demonstrate the signals aliens can receive from Earth, were generated by Ramiro Saide, an intern at the Search for Extraterrestrial Intelligence Institution (SETI) Radio Hat Creek Observatory and a doctoral student at the University of Mauricio, who participated in the investigation.
The simulations also show that the Earth mobile radio signature includes a substantial contribution from developing countries, including Africa, which the scientists say is an exciting development and highlights their success in bypassing the development stage of landline and go straight into the digital age.
Dr. Nalini Heeralall-Issur, Saide’s supervisor and associate professor at the University of Mauritius, said: “Every day we are learning more about the characteristics of exoplanets through space missions such as Kepler and TESS (Transiting Exoplanet Survey Satellite), with more information from the James Webb Space Telescope I think there is a very good chance that advanced civilizations exist, and some may be able to observe human-made radio leakage from planet Earth.”
Next, the research team is willing to expand their research to include Other Contributors to the Earth Radio Leak Signature, such as powerful civilian and military radars, new digital transmission systems, Wi-Fi networks, individual mobile phones and the swarm of satellite constellations now. being launched into low Earth orbit, like Elon Musk’s Starlink system.
