Scientists from The University of Manchester<\/a> and the University of Mauritius<\/a> used crowd sourced data to simulate radio leakage from mobile towers to determine what alien civilisations might detect from various nearby stars, including Barnard’s star, six light years away from Earth.<\/p>\n\n\n\n

The researchers found that only more technologically advanced civilisations would be able to detect the current levels of mobile tower radio leakage from Earth, the universities write in a press release.<\/a> However, as most alien civilisations are likely to have more sensitive receiving systems and as we move towards more powerful broadband systems on Earth, the detectability of humans from other intelligent beings will become more and more likely.<\/p>\n\n\n

‘Earth has become increasingly quiet’ <\/strong><\/h2>\n\n\n\n

Professor Mike Garrett, team leader of the project and director of\u00a0Jodrell Bank Centre for Astrophysics<\/a>\u00a0at The University of Manchester, said: \u201cI\u2019ve heard many colleagues suggest that the Earth has become increasingly radio quiet in recent years – a claim that I always contested. Although it\u2019s true we have fewer powerful TV and radio transmitters today, the proliferation of mobile communication systems around the world is profound. While each system represents relatively low radio powers individually, the integrated spectrum of billions of these devices is substantial.”<\/p>\n\n\n\n

Current estimates suggest we will have more than one hundred thousand satellites in low Earth orbit and beyond before the end of the decade. The Earth is already anomalously bright in the radio part of the spectrum; if the trend continues, we could become readily detectable by any advanced civilisation with the right technology, according to professor Garrett.<\/p>\n\n\n

Signals aliens receive<\/strong><\/h2>\n\n\n\n

The models, which demonstrate the signals that aliens may receive from Earth, were generated by Ramiro Saide, an intern at the\u00a0Search for Extra-terrestrial Intelligence (SETI)<\/a>\u00a0Instution\u2019s\u00a0Hat Creek Radio Observatory. The simulations also show that the Earth\u2019s mobile radio signature includes a substantial contribution from developing countries, including Africa, which the scientists say is an exciting development and highlights its success in bypassing the landline stage of development and moving directly into the digital age.<\/p>\n\n\n\n

Dr Nalini Heeralall-Issur, associate professor at the University of Mauritius, said: \u201cEvery day we learn more about the characteristics of exoplanets via space missions like Kepler and the Transiting Exoplanet Survey Satellite, with further insights from the James Webb Space Telescope. I believe that there\u2019s every chance advanced civilisations are out there, and some may be capable of observing the human-made radio leakage coming from planet Earth.\u201d<\/p>\n\n\n\n

Next, the research team is keen to extend their research to include other contributors to the Earth\u2019s radio leakage signature, such as powerful civilian and military radars, new digital broadcast systems, Wi-Fi networks, individual mobile handsets and the swarm of satellite constellations now being launched into low Earth orbit, such as Elon Musk\u2019s Starlink system. <\/p>\n","protected":false},"excerpt":{"rendered":"
