A new study suggests aliens on neighboring stars may detect Earth’s radio broadcasts.
The University of Manchester and the University of Mauritius used crowd-sourced data to replicate radio leakage from mobile towers to examine what alien civilizations would detect from close stars like Barnard’s star, six light years from Earth. Here’s Why NASA Signals May Have Reached Aliens, But It May Take 27 Years to Respond.
The Monthly Notices of the Royal Astronomical Society journal reported that only sophisticated civilizations could detect Earth’s mobile tower radio leakage.
Despite weaker TV and radio transmitters, mobile communication networks are important worldwide.
“While each system represents relatively low radio powers individually, the integrated spectrum of billions of these devices is substantial,” said Professor Mike Garrett, project leader and Director of Jodrell Bank Centre for Astrophysics at The University of Manchester.
“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,” he said. Aliens Contacting Earth? Scientists Investigating 25 Mysterious “Fast Radio Bursts” From Space.
Ramiro Saide, an M.Phil student at the University of Mauritius and an intern at SETI’s Hat Creek Radio Observatory, created the simulations of Earth’s transmissions to aliens.
Scientists claim Africa’s contributions to the Earth’s mobile radio signature are outstanding and demonstrate the country’s achievement in skipping the landline era and entering the digital age.
“Kepler, the Transiting Exoplanet Survey Satellite, and the James Webb Space Telescope teach us more about exoplanets every day,” stated Dr. Nalini Heeralall-Issur, Associate Professor at the University of Mauritius.
“I believe that there’s every chance advanced civilisations are out there, and some may be capable of observing the human-made radio leakage coming from planet Earth,” she said.
