Scientists revealed that radar systems at airports and military bases emit signals detectable by advanced alien civilizations. Research simulated Earth’s visibility to such civilizations, demonstrating that emissions from civilian airports peak at two billion megawatts, strong enough to be observed from 200 light years away. A civilization only needs to be slightly advanced in technology to detect Earth's signals, suggesting that common radar operations could inadvertently expose humanity's presence to extraterrestrial observers. Professor Garrett indicated that only a few hundred years of technological advancement may be necessary for detection.
Professor Michael Garrett from the University of Manchester states, 'I don't think they need to be more than a few hundred years more advanced than we are.' This indicates that advanced civilizations might not be as far beyond us as we think.
Research showed that radar emissions from Earth's airports reach peak intensities of two billion megawatts. Signals could potentially be detected by alien civilizations from up to 200 light years away.
Simulations conducted reveal that Earth's radar systems, especially at airports like Gatwick and Heathrow, could signal our presence to extraterrestrial observers lurking in space.
The findings suggest that advancements in radio telescope technology, similar to ours, would allow other civilizations to detect the emissions emitted by our radar systems.
