While we search for signs of life beyond Earth, radio signals 'leaked' from our mobile phone towers could be helping extra-terrestrials find us.
According to a new study, these radio signals are not currently strong enough on their own to be detectable by alien civilisations assuming they're using the same technology as we are to find them. But if these civilisations have more advanced technology, and are looking at radiation from additional sources (such as Wi-Fi networks), we could soon be discovered by extra-terrestrials in nearby star systems.
