How to listen for alien life
For more than 60 years, scientists have been on the stealthiest stakeout in history. Using state-of-the-art listening devices, they’ve tapped into thousands of homes, waiting patiently for their targets to reveal their presence, and ultimately been rewarded with silence. If this covert activity were occurring in our own country, one might have become impatient and simply walked up and knocked down the door. But the targets are not living in our country, or even on our planet or in our solar system. Our persons of interest are aliens. This is Seti: the Search for Extraterrestrial Intelligence, focused on life on planets orbiting other suns. So far, we’ve found no sign of them.
