“Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters – things like that.”
Cool!
If there's one thing that I desperately want to have happen in my lifetime, it's the discovery of extra terrestrial life. There is no other thing/idea that is more fascinating to me.
