![]() ![]() This is due to the rotation of our planet and the non-uniform way mobile towers are distributed. Overall, the results show that the Earth's radio leakage signature is periodic and very dependent on the location of the hypothetical observer. Humans May Be Only Intelligent Life in the Universe | Opinionįrom HD 95735-a red dwarf located 8.3 light-years away-meanwhile, the main contribution of these signals would come mainly from the east coast of China, followed by the west and east coasts of North America.įinally, from Alpha Centauri A-located around 4.2 light-years away-the primary contribution would come mainly from the west of Asia and Central Europe, with East Africa and Australia also making significant contributions.Our Minds Could Be Preventing Us From Finding E.T.This Is How We Could Find Advanced Alien Civilizations.For example, an extraterrestrial civilization around Barnard's star-which lies around 6 light-years away-would see the largest peaks in detectable signals when either Western Europe or East Asia first comes into view or finally disappears around the limb of the Earth from its frame of reference. Their results show that alien observers in these locations would detect our signals in slightly different ways. These stars are all located within a few light years of Earth. The team created a model of the leakage and then calculated how this would be seen by any alien observers located at three different viewing points-the "nearby" stars HD 95735, Barnard's star, and Alpha Centauri A. ![]() In their study, which was published in the journal Monthly Notices of the Royal Astronomical Society, the researchers examined the overall contribution of mobile towers across Earth to the radio leakage coming from our planet. Our paper was to try and work out just how much it adds up to-and it's significant." But I felt that wasn't right-that we needed to take into account the new developments of mobile phones, and WiFi-although these are not very powerful, there are just so many of them that it all adds up. "Also, I heard many colleagues say that the Earth had gone radio quiet-because the big radio and TV transmitters were now on cable. "We decided to carry out the research because this topic hadn't been touched since the late 1970s and a lot has changed since then," Michael Garrett, another author of the study from the University of Manchester, United Kingdom, told Newsweek. They created a model of the Earth's radiation and showed that an external observer would see variations in the signal power as different regions of the Earth rotated in and out of view.īut the nature of Earth's radio leakage has changed significantly since the 1970s as technology has advanced. These researchers examined the specific case of our own planet, Earth, and concluded that the most likely form of radio leakage that might be detected by another intelligent civilization was associated with military radar systems and television stations. Would a distant alien civilization be able to detect us? iStock Stock image: Illustration of the Earth in space. ![]()
