Radar systems used by civilian airports and military operations are inadvertently revealing our existence to potential advanced alien civilizations, new research shows.

The study explored how hidden electromagnetic leakage might look to extraterrestrials up to 200 light-years from Earth, if they had state-of-the-art radio telescopes like our own. Theoretically, it also suggests this is how far we would be able to look to spot aliens who have evolved to use a similar level of technology.
